GO Classification
Functions
  • androgen binding
Processes
  • primary spermatocyte growth
Components
  • extracellular region
  • extracellular exosome
General FunctionAndrogen binding
Specific FunctionFunctions 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.
