What is the function of this protein?
Catalyzes the hydrolysis of ATP coupled with the transport of calcium from the cytoplasm to the extracellular space thereby maintaining intracellular calcium homeostasis (PubMed:22311909, PubMed:16956963, PubMed:28827723, PubMed:26392310, PubMed:29950683, PubMed:24805951, PubMed:23266958).  Plays a role in blood pressure regulation through regulation of intracellular calcium concentration and nitric oxide production leading to regulation of vascular smooth muscle cells vasoconstriction (PubMed:24805951, PubMed:29950683, PubMed:22311909).  Positively regulates bone mineralization through absorption of calcium from the intestine (PubMed:23266958, PubMed:26392310).  Plays dual roles in osteoclast differentiation and survival by regulating RANKL-induced calcium oscillations in preosteoclasts and mediating calcium extrusion in mature osteoclasts (PubMed:23266958).  Regulates insulin sensitivity through calcium/calmodulin signaling pathway by regulating AKT1 activation and NOS3 activation in endothelial cells (By similarity).  May play a role in synaptic transmission by modulating calcium and proton dynamics at the synaptic vesicles.
What are the official names of this protein?
Plasma membrane calcium-transporting ATPase 1, Plasma membrane calcium ATPase isoform 1, PMCA1, Plasma membrane calcium pump isoform 1.
What is the protein family that this protein belongs to?

What are the subcellular locations of this protein?
Cell membrane; Multi-pass membrane protein. Basolateral cell membrane. Synapse. Presynaptic cell membrane; Multi-pass membrane protein. Cytoplasmic vesicle, secretory vesicle, synaptic vesicle membrane; Multi-pass membrane protein. Note=Colocalizes with SV2A in photoreceptor synaptic terminals (PubMed:12209837). Colocalizes with NPTN to the immunological synapse (PubMed:28827723). Colocalizes with EPB41 to the basolateral membrane in enterocyte (PubMed:23460639). Preferentially sorted to recycling synaptic vesicles.
