    1. Glycoprotein produced primarily in liver, as well as sertoli cells (Testes), Uterus, placenta, brain
    2. Sex Hormone Binding Globulin (SHBG) binds 17 beta-hydroxysteriod hormones: androgens (e.g. testosterone) and Estrogen
    3. Transcortin, by contrast binds other steroid hormones (Progesterone, Corticosteroids)
  3. Interpretation: Normal Levels
    1. Male: 0.4 to 1.3 ug DHT/100 ml
    2. Female: 0.4 to 3.5 ug DHT/100 ml
    3. Pregnancy: 6.5 to 9.7 ug DHT/100 ml

Sex Hormone-Binding Globulin (C0036883)

Definition (NCI) Expressed as 2 alternative isoforms in Sertoli cells and liver by human SHBG Gene, 402-aa 44-kDa (precursor) homodimeric Sex Hormone-Binding Globulin is a secreted beta-globulin plasma glycoprotein containing 2 laminin G-like domains that specifically bind 5-alpha-dihydrotestosterone, testosterone, or 17-beta-estradiol. An androgen transport protein, SHBG regulates the plasma metabolic clearance rate of steroid hormones by controlling plasma concentration and may be involved in receptor-mediated processes as well. (NCI)
Definition (MSH) A glycoprotein migrating as a beta-globulin. Its molecular weight, 52,000 or 95,000-115,000, indicates that it exists as a dimer. The protein binds testosterone, dihydrotestosterone, and estradiol in the plasma. Sex hormone-binding protein has the same amino acid sequence as ANDROGEN-BINDING PROTEIN. They differ by their sites of synthesis and post-translational oligosaccharide modifications.
