Application Abreviews Notes
WB Use a concentration of 0.3 - 1 µg/ml. Detects a band of approximately 26 kDa (predicted molecular weight: 28 kDa).Can be blocked with SRD5A2 peptide (2-13) (ab45681).
ICC/IF Use at an assay dependent concentration.


  • FunctionConverts testosterone (T) into 5-alpha-dihydrotestosterone (DHT) and progesterone or corticosterone into their corresponding 5-alpha-3-oxosteroids. It plays a central role in sexual differentiation and androgen physiology.
  • Tissue specificityExpressed in high levels in the prostate and many other androgen-sensitive tissues.
  • Involvement in diseaseDefects in SRD5A2 are the cause of pseudovaginal perineoscrotal hypospadias (PPSH) [MIM:264600]. A form of male pseudohermaphroditism in which 46,XY males show ambiguous genitalia at birth, including perineal hypospadias and a blind perineal pouch, and develop masculinization at puberty. The name of the disorder stems from the finding of a blind-ending perineal opening resembling a vagina and a severely hypospadiac penis with the urethra opening onto the perineum.
