Plasma membrane calcium-transporting ATPase 3

UniProtKB accession:  Q16720

Grouped By:  Matching UniProtKB accession

UniProtKB description:  ATP-driven Ca(2+) ion pump involved in the maintenance of basal intracellular Ca(2+) levels at the presynaptic terminals (PubMed:18029012, PubMed:22912398, PubMed:25953895, PubMed:27035656). Uses ATP as an energy source to transport cytosolic Ca(2+) ions across the plasma membrane to the extracellular compartment (PubMed:25953895, PubMed:27035656). May counter-transport protons, but the mechanism and the stoichiometry of this Ca(2+)/H(+) exchange remains to be established (By similarity).
