Summaries for ATP8B1 Gene

Entrez Gene Summary for ATP8B1 Gene

  • This gene encodes a member of the P-type cation transport ATPase family, which belongs to the subfamily of aminophospholipid-transporting ATPases. The aminophospholipid translocases transport phosphatidylserine and phosphatidylethanolamine from one side of a bilayer to another. Mutations in this gene may result in progressive familial intrahepatic cholestasis type 1 and in benign recurrent intrahepatic cholestasis. [provided by RefSeq, Jul 2008]

GeneCards Summary for ATP8B1 Gene

ATP8B1 (ATPase Phospholipid Transporting 8B1) is a Protein Coding gene. Diseases associated with ATP8B1 include Cholestasis, Progressive Familial Intrahepatic 1 and Cholestasis, Benign Recurrent Intrahepatic. Among its related pathways are Ion channel transport and Cardiac conduction. GO annotations related to this gene include nucleotide binding and cation-transporting ATPase activity. An important paralog of this gene is ATP10A.

UniProtKB/Swiss-Prot for ATP8B1 Gene

  • Catalytic component of a P4-ATPase flippase complex which catalyzes the hydrolysis of ATP coupled to the transport of aminophospholipids from the outer to the inner leaflet of various membranes and ensures the maintenance of asymmetric distribution of phospholipids. Phospholipid translocation seems also to be implicated in vesicle formation and in uptake of lipid signaling molecules. May play a role in asymmetric distribution of phospholipids in the canicular membrane. May have a role in transport of bile acids into the canaliculus, uptake of bile acids from intestinal contents into intestinal mucosa or both. In cooperation with ABCB4 may be involved in establishing integrity of the canalicular membrane thus protecting hepatocytes from bile salts. Together with TMEM30A is involved in uptake of the synthetic drug alkylphospholipid perifosine. Involved in the microvillus formation in polarized epithelial cells; the function seems to be independent from its flippase activity. Required for the preservation of cochlear hair cells in the inner ear. May act as cardiolipin transporter during inflammatory injury.

  • Cholestasis of pregnancy, intrahepatic 1 (ICP1) [MIM:147480]: A liver disorder of pregnancy. It presents during the second or, more commonly, the third trimester of pregnancy with intense pruritus which becomes more severe with advancing gestation and cholestasis. Cholestasis results from abnormal biliary transport from the liver into the small intestine. ICP1 causes fetal distress, spontaneous premature delivery and intrauterine death. ICP1 patients have spontaneous and progressive disappearance of cholestasis after delivery. {ECO:0000269 PubMed:15657619, ECO:0000269 PubMed:15888793}. Note=The disease may be caused by mutations affecting the gene represented in this entry.
  • Cholestasis, benign recurrent intrahepatic, 1 (BRIC1) [MIM:243300]: A disorder characterized by intermittent episodes of cholestasis without progression to liver failure. There is initial elevation of serum bile acids, followed by cholestatic jaundice which generally spontaneously resolves after periods of weeks to months. The cholestatic attacks vary in severity and duration. Patients are asymptomatic between episodes, both clinically and biochemically. {ECO:0000269 PubMed:15239083, ECO:0000269 PubMed:9500542, ECO:0000269 PubMed:9918928}. Note=The disease is caused by mutations affecting the gene represented in this entry.
