Solute carrier protein that negatively regulates the cytosolic calcium homeostasis in response to high levels of extracellular calcium. Distributes as multiple foci in the plasma membrane prior to cell division, moves toward and concentrates at the bud neck as the bud grows in size, and disperses again along the plasma membrane immediately prior to cytokinesis. Expression is positively regulated by calcium/calcineurin signaling through the sole CDRE element (5'-TTAGCCTC-3') in its promoter. Belongs to the bile acid:sodium symporter (BASS) (TC 2.A.28) family.
