This category deals with cytobiology;
protein interactions at the cellular level, such as cytoplasm or organelles
in contrast to those at the nuclear level,
which are dealt with in Gene Expression.
The established pathways, also known as Enzymology, are currently dealt with in the Metabolism category
However, structural aspects are included in Proteins and Enzymes: Structure.
where there are also links about the enzymes of transcription and translocation.
Whereas intracellular events related to cytoplasm are contained in this category,
intercellular events effecting membrane, signaling mechanisms and second messengers,
should be found in Cell_Biology,
or perhaps Developmental_Biology.
Biochemical events between organs should be found in Physiology,
or perhaps Endocrinology.

Submissions on cytobiology of proteins, including receptors and postranslational modification, such as phosphorylation

that are insufficiently specialized for the Proteomics category

For sites where the primary focus is on three dimensional structure, consider Proteins and Enzymes: Structure.

more information (editors only)

Sites for books, literature reviews, journals and newsletters, with contents primarily on the structural aspects of proteins, and their structure activity relationships.

Sites promoting Books are not normally listed in ODP unless there is substantial content; at least one sample chapter readable on the site.


Sites for proteins that have not required genetically modified organisms, or cell-free expression systems should be submitted to the Business . . Proteins category.
Sites exclusively about proteins for biotherapeutic or other medical use should be submitted to links or a sub-category of Biopharmaceuticals.

Proteomics is the study of the proteome, the entire complement of proteins expressed by a genome, cell, tissue or organism. A cellular proteome is the collection of proteins found in a particular cell type under a particular set of environmental conditions. An organism's complete proteome is the complete set of proteins from all of the various cellular proteomes.
Please submit only websites that have English language content. If your site is in a language other than English, please submit it to the appropriate category of World.
This category includes sites that relate to the details and methods for determining the structure of proteins.
