Anti-KRIZI antibodies enable researchers to detect and measure the KRIZI antigen in biological samples. This target is a reported synonym of the SRD5A3 gene, which encodes steroid 5 alpha-reductase 3. This protein is known to function in metabolic processes, among other biological roles. The human version of KRIZI has a canonical amino acid length of 318 residues and a protein mass of 36.5 kilodaltons. It is reported to be localized in the ER of cells. KRIZI is a member of the Steroid 5-alpha reductase protein family.
