Atp8a2 Gene Summary [Rat]
Predicted to enable aminophospholipid flippase activity. Acts upstream of or within neuron projection development. Predicted to be located in several cellular components, including Golgi apparatus; endosome; and nucleoplasm. Predicted to be part of phospholipid-translocating ATPase complex. Predicted to be active in plasma membrane and trans-Golgi network. Human ortholog(s) of this gene implicated in cerebellar ataxia, impaired intellectual development, and dysequilibrium syndrome 4. Orthologous to human ATP8A2 (ATPase phospholipid transporting 8A2). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Atp8a2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
