General Information and Variability Data of DT
DT ID DTD0391
Gene Name SLC51A
Protein Name Organic solute transporter subunit alpha
Synonyms OST-alpha; OSTA; OSTalpha; SLC51A; Solute carrier family 51 subunit alpha
Gene ID
200931
UniProt ID
Q86UW1
TCDB ID
2.A.82.1.2
DT Family Organic Solute Transporter (OST) Family ;
Tissue Specificity Widely expressed with a high expression inileum. Expressed in testis, colon, liver, small intestine, kidney,ovary and adrenal gland; and at low levels in heart, lung, brain,pituitary, thyroid gland, uterus, prostate, mammary gland and fat.
Function This transporter is essential component of the Ost-alpha/Ost-beta complex, a heterodimer that acts as the intestinal basolateral transporter responsible for bile acid export from enterocytes into portal blood. Efficiently transports the major species of bile acids.
