CC -!- FUNCTION: Catalytic component of a P4-ATPase flippase complex which
CC catalyzes the hydrolysis of ATP coupled to the transport of
CC phospholipids, in particular phosphatidylcholines (PC), from the outer
CC to the inner leaflet of the plasma membrane (By similarity). May
CC participate in the establishment of the canalicular membrane integrity
CC by ensuring asymmetric distribution of phospholipids in the canicular
CC membrane (PubMed:21820390). Thus may have a role in the regulation of
CC bile acids transport into the canaliculus, uptake of bile acids from
CC intestinal contents into intestinal mucosa or both and protect
CC hepatocytes from bile salts (PubMed:14976163, PubMed:21820390,
CC PubMed:20126555). Involved in the microvillus formation in polarized
CC epithelial cells; the function seems to be independent from its
CC flippase activity (By similarity). Participates in correct apical
CC membrane localization of CDC42, CFTR and SLC10A2 (PubMed:26416959).
CC Enables CDC42 clustering at the apical membrane during enterocyte
CC polarization through the interaction between CDC42 polybasic region and
CC negatively charged membrane lipids provided by ATP8B1
CC (PubMed:26416959). Together with TMEM30A is involved in uptake of the
CC synthetic drug alkylphospholipid perifosine (By similarity). Required
CC for the preservation of cochlear hair cells in the inner ear
CC (PubMed:19478059). According PubMed:20852622 is proposed to act as
CC cardiolipin transporter during inflammatory injury; the function is
CC questioned by PubMed:21475228 (PubMed:20852622, PubMed:21475228).

CC catalytic alpha subunit ATP8B1 and an accessory beta subunit TMEM30A
CC (PubMed:30018401). The flippase ATP8B1:TMEM30A complex can form an
CC intermediate phosphoenzyme in vitro. Also interacts with beta subunit

CC {ECO:0000250|UniProtKB:O43520}. Golgi apparatus
CC {ECO:0000250|UniProtKB:O43520}. Note=Exit from the endoplasmic
CC reticulum requires the presence of TMEM30A or TMEM30B. Localizes to
CC apical membranes in epithelial cells. {ECO:0000250|UniProtKB:O43520}.
CC -!- TISSUE SPECIFICITY: Hepatocytes, bile duct, intestinal epithelial cells
CC (cholangiocytes and ileocytes), and pancreatic acinar cells.
CC {ECO:0000269|PubMed:14976163, ECO:0000269|PubMed:30018401}.
CC -!- DISRUPTION PHENOTYPE: Mice have unimpaired bile secretion, and no liver
CC damage, but show mild abnormalities including depressed weight at
CC weaning and elevated serum bile salt levels. Do not suffer from
CC jaundice or diarrhea and have normal serum bilirubin levels and normal
CC liver enzyme activities, except for mildly elevated serum AST
CC (aspartate aminotransferase) activity. Display unimpaired transhepatic
CC bile salt transport and are resistant to bile salt-induced cholestasis.
CC Upon bile salt feeding, demonstrate serum bile salt accumulation,
CC hepatic injury and expansion of the systemic bile salt pool and this
CC failure of bile salt homeostasis occurs in the absence of any defect in
CC hepatic bile secretion (PubMed:14976163). Mutant mice with B6
CC background show greater abnormalities than 129 and/or F1 background
CC ones. Pups of B6 background gain less weight. In adult B6 background
CC has lower serum cholesterol levels, higher serum alkaline phosphatase
CC levels, and larger livers. After challenge with cholate-supplemented
CC diet, these mice exhibit higher serum alkaline phosphatase and
CC bilirubin levels, greater weight loss and larger livers
CC (PubMed:20126555). {ECO:0000269|PubMed:14976163,
CC ECO:0000269|PubMed:20126555}.
CC -!- SIMILARITY: Belongs to the cation transport ATPase (P-type) (TC 3.A.3)
CC family. Type IV subfamily. {ECO:0000305}.
