Solute carrier protein that negatively regulates the cytosolic 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. Leads to modest tolerance to azoles and terbinafine, but not to amphotericin B and nystatin (PubMed:22530691). Elevates the intracellular Ca(2+) and leads to the activation of the calcium/calcineurin signaling pathway (PubMed:22530691). Belongs to the bile acid:sodium symporter (BASS) (TC 2.A.28) family.
