---|---|
Target/Specificity | SHBG antibody was raised against a 16 amino acid peptide near the center of human SHBG. The immunogen is located within amino acids 220 - 270 of SHBG. |
Reconstitution & Storage | Antibody can be stored at 4°C up to one year. Antibodies should not be exposed to prolonged high temperatures. |
Precautions | SHBG Antibody is for research use only and not for use in diagnostic or therapeutic procedures. |
Name | SHBG (HGNC:10839) |
---|---|
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. |
Cellular Location | Secreted. Note=In testis, it is synthesized by the Sertoli cells, secreted into the lumen of the seminiferous tubule and transported to the epididymis. |
Tissue Location | Isoform 1 and isoform 2 are present in liver and testis |

Background
SHBG is a steroid binding protein that was first described as a plasma protein secreted by the liver and is thought to participate in the regulation of steroid responses. SHBG transports androgens and estrogens in the blood, binding each steroid molecule as a dimer formed from identical or nearly identical monomers (1). Low plasma SHBG levels are associated with obesity, abdominal adiposity, metabolic syndrome, and predict the development of type 2 diabetes (2,3). Polymorphisms in this gene have been associated with polycystic ovary syndrome and type 2 diabetes mellitus (4).
