[5][6] The protein encoded by this gene belongs to the family of P-type primary ion transport ATPases characterized by the formation of an aspartyl phosphate intermediate during the reaction cycle.

The mammalian plasma membrane calcium ATPase isoforms are encoded by at least four separate genes and the diversity of these enzymes is further increased by alternative splicing of transcripts.

This gene encodes the plasma membrane calcium ATPase isoform 4.

Alternatively spliced transcript variants encoding different isoforms have been identified.
