FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Polyspecific organic cation transporters in the liver, kidney, intestine, and other organs are critical for elimination of many endogenous small organic cations as well as a wide array of drugs and environmental toxins. The encoded protein is an organic cation transporter and plasma integral membrane protein containing eleven putative transmembrane domains as well as a nucleotide-binding site motif. Transport by this protein is at least partially ATP-dependent. [provided by RefSeq, Jul 2008]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit complete loss of ergothioneine with reduced absorption and increased excretion and increased susceptibility of small intestine to inflammation following ischemia and reperfusion. [provided by MGI curators]
