Research Categories


The Protein Journal (formerly the Journal of Protein Chemistry) publishes original research work on all aspects of protein investigations. These include studies concerned with the structure (covalent or three-dimensional), assembly, genetics, evolution, proteomics, molecular biology, engineering, peptide synthesis or the application of these studies to the elucidation and interpretation of the molecular bases of the biological activity of proteins. All facets of protein biological functions and interactions are appropriate.

Impact Factor

Impact factor (IF) is a scientometric factor based on the yearly average number of citations on articles published by a particular journal in the last two years. A journal impact factor is frequently used as a proxy for the relative importance of a journal within its field. Find out more: What is a good impact factor?

III. Other Science Influence Indicators

Any impact factor or scientometric indicator alone will not give you the full picture of a science journal. There are also other factors such as H-Index, Self-Citation Ratio, SJR, SNIP, etc. Researchers may also consider the practical aspect of a journal such as publication fees, acceptance rate, review speed.

Protein Journal

The h-index is an author-level metric that attempts to measure both the productivity and citation impact of the publications of a scientist or scholar. The index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications
