The human gene ATP8B3 encodes the protein ATPase, aminophospholipid transporter, class I, type 8B, member 3.^[5]

Transcript

Alternatively spliced transcript variants encoding different isoforms have been found for this gene.^[5]

Protein

The protein encoded by this gene belongs to the family of P-type cation transport ATPases, and to the subfamily of aminophospholipid-transporting ATPases. The aminophospholipid translocases transport phosphatidylserine and phosphatidylethanolamine from one side of a bilayer to another. This gene encodes the member 3 of the phospholipid-transporting ATPase 8B.
