Predicted to enable ATP binding activity; ATP hydrolysis activity; and P-type calcium transporter activity. Predicted to be involved in calcium ion transmembrane transport. Predicted to be located in membrane. Is an ortholog of C. elegans mca-3. In C. elegans, mca-3 is involved in several processes, including negative regulation of cytosolic calcium ion concentration; nematode larval development; and positive regulation of growth rate.
