Application Abreviews Notes
WB Use at an assay dependent concentration. Detects a band of approximately 44 kDa (predicted molecular weight: 44 kDa).


  • Function

    Functions as an androgen transport protein, but may also be involved in receptor mediated processes. Each dimer binds one molecule of steroid. Specific for 5-alpha-dihydrotestosterone, testosterone, and 17-beta-estradiol. Regulates the plasma metabolic clearance rate of steroid hormones by controlling their plasma concentration.
  • Tissue specificity

    Isoform 1 and isoform 2 are present in liver and testis.
  • Sequence similarities

    Contains 2 laminin G-like domains.
  • Cellular localization

    Secreted. In testis, it is synthesized by the Sertoli cells, secreted into the lumen of the seminiferous tubule and transported to the epididymis.
