Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Pmpca often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- metallopeptidase
- endopeptidase
- peptidase
- mitochondrial processing peptidase
- protein binding
- Insulinase (Peptidase family M16)
