GENERAL GUIDELINES

Scope
Molecules and Cells (Mol. Cells) is an international journal devoted to the advancement and dissemination of fundamental knowledge concerning the molecular biology of cells. Papers on a broad range of topics of general interest to molecular and cell biologists are published. The journal will not publish paper that simply reports the cloning and sequencing of a gene or the preliminary X-ray crystallography without providing evidence for its biological significance. It is published monthly by the Korean Society for Molecular and Cellular Biology (KSMCB) and distributed by Springer.

Submission of Papers
All submissions to Mol. Cells must be made electronically via the web-enable online manuscript submission and review system: www. molcells.org (E-mail submissions will not be accepted.). Information regarding acceptable types of files for submission can be found on the on-line submission page of the journal homepage. It is recommended that all tables and figures be assembled into a single file together with the main text when submitted.
The manuscript must be accompanied by a cover letter stating the title of the manuscript, names of each author, and complete mailing address(es), telephone and fax number(s) of the corresponding author, electronic mail address(es) if available.
Manuscripts should be double-spaced and all pages, including the abstract, figures, and tables, should be numbered in sequence, Manuscript pages must have margins of at least 2.5 cm on all four sides. Authors who are not confident of their English writing should have checked their manuscripts by an English proofreader.
All queries regarding the submission should be directed to the editorial office.

Minireviews
Minireviews are brief summaries of developments in fast moving areas. They must be based on published articles, and may address any subject within the scope of Mol. Cells. Minireviews are invited by the editors, not solicited, and are not subject to editorial review.
Anyone, wishing to submit minireviews, should provide a potential title and subject of the review article to the editor to seek permission.

Communications
Communications are intended to present new information of exceptional interest and novelty to readers of the JOURNAL. They are not intended to be short versions of Regular Papers. Because the criteria for acceptance of Communication are stringent and the review process is expedited, an Associate Editor may judge a manuscript unsuitable without obtaining a full review.

EDITORIAL POLICY

Originality
scientific findings in molecular and cellular biology will be considered and accepted for publication. Manuscripts submitted to Mol. Cells must represent reports of original research. A manuscript will be accepted on the conditions that the presented work was not published previously, and is not under consideration for publication elsewhere.

Authorship
Anyone who made a substantial contribution to the work may be included in the author list. All authors of each manuscript are responsible for the entire paper and must have agreed that the corresponding author has the authority to act on their behalf on all matters pertaining to publication of the manuscript. To avoid any possible dispute during processing, authorship changes including the order of authors’ names during revision must be agreed upon by all of the authors and brought to the editor’s attention in the cover letter submitted with the revised version.

Ethical Aspects
Manuscripts dealing with any experimental work on human or animal materials should meet the relevant regulations or requirements imposed by institutional or governmental authorities, and this should be clearly stated in the manuscript. Copies of these regulations and guidelines must be available for review by the editor if necessary. The editor reserves the right to reject papers if ethical aspects are in doubt.

Nucleotide and Amino Acid Sequences
Any novel nucleotide or amino acid sequences described should be deposited in a public database, such as GenBank, EMBL or DDBJ, and the accession numbers should be included in a separate paragraph in the Materials and Methods section. It is expected that the sequence data will be publicly available no later than the publication of the article.

Review Process
All manuscript are reviewed confidentially by members of the editorial board and qualified reviewers. When a manuscript and is submitted to Mol. Cells, it is given a manuscript number and assigned to one of the members of the board for review. The manuscript number should be referred to in any subsequent communications between the corresponding author and the the editor or the editorial office. The reviewers operate under the guidelines for reviewers and are expected to complete their reviews as soon as possible. The corresponding author is generally notified of the reviewers’ decision, accepted, rejected, revision recommended, revision or re-review recommended from the editorial office within 4 weeks of submission. When a manuscript is returned revision, is should be returned to the editor within 3 months, or it may be considered withdrawn. The authors should supply the response to the editor along with the modified or revised manuscript. Manuscripts that have been rejected or withdrawn may be resubmitted if the major criticisms have been properly addressed. As with the initial submission, resubmitted manuscripts should be accompanied by a cover letter stating the manuscript is resubmission and describing in detail what changes have been made. The same editor that handled the original submission will normally handle the resubmitted manuscript.

Notification of Acceptance
When an editor has decided that a manuscript is acceptable for publication, the corresponding author and the editorial office will be notified. The editorial office will check if the manuscript was prepared according to the guidelines, however the authors are primarily responsible for the format and quality of the paper. The editor of Mol. Cells will complete the assignment of editing after the manuscript is considered to meet the prescribed standards.

Galley Proofs
The editorial office sends a galley proof, a reprint order form, and a copyright transfer statement form to the corresponding author. Galley proof should be corrected, signed by the corresponding author and send back to the editorial office within 48 hours, however extensive corrections, additions, or deletions should not be made during the proof stage. Important new information or references of unpublished data or personal communications that have become available in the time between acceptance of the manuscript and receipt of the proofs may be inserted with the permission of the editor. Otherwise, changes are limited to correction of spelling errors, incorrect data, grammatical errors and updated information regarding references.

Page Charge
Page Charge are currently 40,000 (member)/45,000 (non-member) Korean won per page. Color charge are 200,000 Korean won per page.

Reprints
Fifty copies of reprints are provided free of charge and sent to the corresponding author. Extra copies (in multiples of 50) can be ordered and purchased through the reprint order form sent to the corresponding author.

ORGANIZATION AND FORMAT

General Organization
The most desirable plan for the organization of a paper is as follows: (a) Abstract, in less than 250 words, (b) Introduction, in less than two typed pages, (c) Materials and Methods, (d) Results, (e) Discussion, (f) Acknowledgments, (g) References. In some cases the presentation might be more effective if you combined some sections, e.g. Results and Discussion. This is particularly true in short papers. The Journal imposes no lower limit on the size of regular papers.

1. The title should be informative and as short as is consistent with clarity. The numbering of parts in a series of papers is not permitted.
   
2. List full names of all authors. A footnote to an author, indicating a change of address, should be given on the title page using one of the following superscript: 1, 2, 3. The asterisk symbol * should be reserved for the author to whom correspondence should be addressed.
   
3. List the institutions in which the work was carried out. Identify the affiliations of all authors and their institutions, departments, or organizations by use of superscript lower case alphabets.
   
4. Provide a short running title of less than 60 characters.

Abstract
The abstract should not exceed 250 words, and should concisely summarize the basic content of the paper. Experimental details should not be presented in the abstract. Avoid specialized terms, abbreviations, diagrams, and references. When it is essential to include a reference, put the literature citation within square brackets, e.g. [Lee and Kang (1990)].

Introduction
It states the purpose of the investigation and its relation to other works in the same field, but should not present an extensive review of the literature.

Materials and Methods
The descriptions in materials and methods should be brief, but sufficiently detailed to permit repetition of the work by a qualified operator. When centrifugation conditions are critical, give details to enable another investigator to repeat the procedure: make of centrifuge, model of rotor, temperature, time at maximum speed, and centrifugal force (´ g rather than revolutions per minutes.).
Refer to published procedures by citing both the original description and pertinent published modifications. Do not include extensive details unless they constitute a significant new modification. A simple reference is sufficient for commonly used materials and methods (e.g. media and protein determination). If several alternative methodologies are commonly employed, it is useful to identify the method briefly, as well as to cite the reference. For example, “cells were broken by ultrasonic treatment as previously described (Kim, 1983)”, rather than “cells were broken as previously described (Kim, 1983)”.
Describe new methods completely and give sources of unusual chemicals, equipment, or microbial strains. When large numbers of microbial strains or mutants are used in a study, include strain tables identifying the sources and properties of the strains, mutants, bacteriophages, plasmids, etc. A method, strain, etc. used in only one of several experiments reported in the paper may be described in the Results section, or very briefly (in one or two sentences) in a table footnote or figure legend.

Results
It should describe the results of the experiments. Reserve extensive interpretation for the Discussion section. Present the results as concisely as possible in one of the following: text, table(s), or figure(s). Avoid presenting essentially similar data in both table and figure form. Also avoid extensive use of graphs to present data that might be more concisely presented in the text or tables. For example, except in unusual cases, double-reciprocal plots used to determine apparent Km values should not be presented as graphs; instead, the values should be stated in the text. Limit photographs (particularly photomicrographs, electron micrographs, and photographs of gel patterns) to those that are absolutely necessary for presenting the experimental findings. Number figures and tables according to the order of citation in the text.

Discussion
It should be concise and provide an interpretation of the results in relation to previously published work and to the experimental system at hand. It should not contain extensive repetition of the Results section or reiteration of the Introduction.

Acknowledgments
Acknowledge personal assistance and financial assistance in the same paragraphs. The usual format for grant support is as follows: “This work was supported by Basic Research grant 891-0301-016-2 from Korea Science and Engineering Foundation.”

Citationsof relevant published work in the text, from Introduction to Discussion, including tables and figures, should read Kim and Kang (1987) or (Kim and Kang, 1987). When a paper cited has three or more authors, use the style Chung et al. (1989) or (Chung et al., 1989). Use (Park, 1983a) and (Park, 1983b) when citing more than one paper by the same author(s) published in the same year. For example, “This is observed both in vivo and in vitro (Choi et al., 1980; Lee, 1989a; Smith and Jones, 1984).”

References
It should include only articles that are published or in press. Unpublished data, submitted manuscripts, abstracts, and personal communications should be cited within the text only. Personal communication should be documented by a letter of permission. Submitted articles should be cited as unpublished data, data not shown, or personal communication. Please use the following style for references.

Tables should be numbered consecutively with Arabic numbers in order of appearance in the text. Type each table double-spaced on a separate page with s short descriptive title typed directly above and with essential footnotes below. Footnotes to tables should be identified with the italic superscript lower case and placed at the bottom of the table.

Figure legends should provide enough information for the figure to be understandable without frequent reference to the text. However, describe detailed experimental methods in the Materials and Methods sections, not in the figure legend. A method that is unique to one of several experiments may be reported in a legend if it can be described very briefly (in one or two sentences). Define all symbols and abbreviations used in the figure that have not been defined elsewhere.
