ATP8A1

The P-type adenosinetriphosphatases (P-type ATPases) are a family of proteins which use the free energy of ATP hydrolysis to drive uphill transport of ions across membranes. Several subfamilies of P-type ATPases have been identified. One subfamily catalyzes transport of heavy metal ions. Another subfamily transports non-heavy metal ions (NMHI). The protein encoded by this gene is a member of the third subfamily of P-type ATPases and acts to transport amphipaths, such as phosphatidylserine. Two transcript variants encoding different isoforms have been found for this gene.

Interaction

Component of a P4-ATPase flippase complex which consists of a catalytic alpha subunit and an accessory beta subunit (PubMed:31416931). Interacts with TMEM30A to form a flippase complex; this complex forms an intermediate phosphoenzyme (PubMed:20947505, PubMed:20961850, PubMed:21914794, PubMed:31416931). Interacts with TMEM30B; this interaction is reported conflictingly (PubMed:20961850).
