FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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]
PHENOTYPE: Homozygous mice display abnormal bile salt homeostasis, normal bile secretion, and an impaired ability to handle increased bile salt loading resulting in liver damage and weight loss on a bile salt supplemented diet. [provided by MGI curators]
