Serpina5 Gene Summary [Rat]
Enables serine-type endopeptidase inhibitor activity. Involved in negative regulation of proteolysis and seminal vesicle development. Predicted to be located in several cellular components, including external side of plasma membrane; extracellular exosome; and secretory granule. Predicted to be part of several cellular components, including protein C inhibitor-KLK3 complex; protein C inhibitor-PLAT complex; and protein C inhibitor-PLAU complex. Predicted to be active in extracellular space. Orthologous to human SERPINA5 (serpin family A member 5). [provided by Alliance of Genome Resources, Jul 2025]

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 Serpina5 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
