Secondary Information

Presence in other biological fluids/tissue/cells brain, liver, and kidney; detected in the brain capillary endothelium in humans;
Protein Function drug uptake transporter; mediate the cellular uptake of a large number of structurally divergent compounds; play a critical role in the central nervous system penetration of many drugs and hormones across the blood-brain barrier
Biochemical Properties broad substrate specificity- Substrates of OATP1A2 include endogenous compounds such as bile acids, steroid hormones, and their conjugates, thyroid hormones, as well as drugs including fexofenadine, ouabain, peptides (e.g. deltorphin II, [D-penicillamine2,5]enkephalin, DPDPE), and the toxin, microcystin
Significance in milk play pivotal roles in the delivery of e.g. vitamins, fatty acids, sterols, porphyrins, thyroid hormones, carnitine, and amino acids to the breast-fed offspring; mediate active transport also of drugs and toxic chemicals into milk
PTMs when expressed in HeLa cells, five putative N-glycosylation sites were identified, including Asn residues at the amino acid positions of 62, 124, 412, and 483 as well as the 135 position
Site(s) of PTM(s)

N-glycosylation, O-glycosylation,
