Within the InterPro resources a protein family is defined as distinct functional, structural or sequence units that may exist in a variety of biological contexts. A match to an InterPro entry of this [..]

The level of protein structure in which combinations of Secondary Protein Structures (alpha helices, beta sheets, loop regions, and motifs) pack together to form folded shapes called domains. Disulfid [..]

Protein Domains that are enriched in Proline. The cyclical Nature of Proline causes the peptide bonds it Forms to have a limited degree of conformational mobility. Therefore the presence of multiple P [..]

A region of a protein responsible for a particular function, as recognized experimentally and by the occurrence of similar segments in other proteins sharing that function, e.g., a DNA binding domain.

Sections of protein sequence (<100 amino acids) that can fold into a specific three-dimensional structure; folding in each domain is typically independent of other domains in the protein. © [..]

A structurally and functionally defined protein region. In proteins with multiple domains, the combination of the domains determines the function of the protein.
