UniprotKB/SwissProt ID: Q9QXZ6 (Q9QXZ6)
Gene Name:
Slco1a1
Organism: Mus musculus (Mouse)
Function: Mediates the Na(+)-independent transport of organic anions such as steroid sulfate conjugates (dehydroepiandrosterone sulfate (DHEAS), 17-beta-glucuronosyl estradiol, estrone-3-sulfate), conjugated (taurocholate) and unconjugated (cholate) bile acids, prostaglandin E2 (PGE2) and L-thyroxine T4 (PubMed:10600646, PubMed:11267661). Also capable of transporting sulfobromophthalein (BSP), ouabain and gadoxetate (PubMed:10600646). Hydrogencarbonate/HCO3(-) acts as the probable counteranion that exchanges for organic anions (By similarity). Shows a pH-sensitive substrate specificity which may be ascribed to the protonation state of the binding site and leads to a stimulation of substrate transport in an acidic microenvironment (By similarity)
