Facts about Phospholipid-transporting ATPase IC.
May play a role in asymmetric distribution of phospholipids in the canicular membrane. May have a role in transport of bile acids into the canaliculus, uptake of bile acids from intestinal contents to intestinal mucosa or both.

Found in most tissues except brain and skeletal muscle. Most abundant in pancreas and small intestine.
Cell membrane; Multi-pass membrane protein. Apical cell membrane. Cell projection, stereocilium. Endoplasmic reticulum. Golgi apparatus. Exit from the endoplasmic reticulum requires the presence of TMEM30A or TMEM30B (PubMed:20947505). Localizes to apical membranes in epithelial cells (PubMed:20512993).
