Summary: Enables phosphatidylserine flippase activity. Predicted to be involved in several processes, including apical protein localization; nervous system development; and phospholipid transport. Predicted to act upstream of or within bile acid metabolic process. Located in brush border membrane.

the predominant P4 ATPases in pure pancreatic beta cells and human and rat pancreatic islets were ATP8B1, ATP8B2, and ATP9A. ATP8B1 and CDC50A were highly concentrated in ISG

ATP8B1, a P-type aminophospholipid translocase, is enriched in cerebral microvessels and may have a role in plasma membrane lipid transport
Title: Identification of ATP8B1 as a blood-brain barrier-enriched protein.
PFIC1 mutations lead to the complete absence of canalicular expression, whereas in BRIC1/ICP residual protein is expressed in the canalicular membrane.
Title: Differential effects of progressive familial intrahepatic cholestasis type 1 and benign recurrent intrahepatic cholestasis type 1 mutations on canalicular localization of ATP8B1.
ATP8B1 deficiency predisposes to cholestasis by favoring bile acid-induced injury in the canalicular membrane but does not directly affect FXR expression
Title: ATP8B1 deficiency disrupts the bile canalicular membrane bilayer structure in hepatocytes, but FXR expression and activity are maintained.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
