Catalyzes the import of organic anions such as taurocholate and estrone sulfate in an ATP-dependent manner (PubMed:12379217). In vitro, also imports ochratoxin A (PubMed:12379217). In addition mediates the cholesterol efflux in an apolipoprotein independent manner an plays a role in sphingomyelin production in oligodendrocytes (PubMed:23560799).2 Publications
Catalyzes the cholesterol and taurocholate efflux in an ATP-dependent manner (PubMed:29300488). Through the interaction with ABCA1 potentiates the cholesterol efflux to lipid-free APOA1, in turn regulates high-density lipoprotein cholesterol levels (PubMed:28882873).2 Publications

    <p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
