GeneID: 5244 Human ABCB4

Swiss-port # P21439 Human Phosphatidylcholine translocator ABCB4

Gene Symbol ABCB4
Gene Full Name ATP-binding cassette, sub-family B (MDR/TAP), member 4
Background The membrane-associated protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the MDR/TAP subfamily. Members of the MDR/TAP subfamily are involved in multidrug resistance as well as antigen presentation. This gene encodes a full transporter and member of the p-glycoprotein family of membrane proteins with phosphatidylcholine as its substrate. The function of this protein has not yet been determined; however, it may involve transport of phospholipids from liver hepatocytes into bile. Alternative splicing of this gene results in several products of undetermined function. [provided by RefSeq, Jul 2008]
Function Mediates ATP-dependent export of organic anions and drugs from the cytoplasm. Hydrolyzes ATP with low efficiency. Not capable of conferring drug resistance. Mediates the translocation of phosphatidylcholine across the canalicular membrane of the hepatocyte. [UniProt]
Calculated MW 142 kDa
PTM Phosphorylated (PubMed:24723470). Phosphorylation on Thr-34 is required for PC efflux activity. Phosphorylation occurs on serine and threonine residues in a protein kinase A- or C-dependent manner (PubMed:24723470). May be phosphorylated on Thr-44 and Ser-49 (PubMed:24723470).
Glycosylated (PubMed:17523162, PubMed:24723470, PubMed:21820390).
