Srd5a2 Gene Summary [Mouse]
Enables 3-oxo-5-alpha-steroid 4-dehydrogenase activity. Involved in androgen biosynthetic process. Acts upstream of or within male genitalia development and steroid biosynthetic process. Predicted to be located in cell body fiber and neuronal cell body. Predicted to be active in endoplasmic reticulum membrane. Is expressed in genitourinary system. Human ortholog(s) of this gene implicated in hypospadias and prostate cancer. Orthologous to human SRD5A2 (steroid 5 alpha-reductase 2). [provided by Alliance of Genome Resources, Apr 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 mouse Srd5a2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
