Has calcium-dependent phospholipid scramblase activity; scrambles phosphatidylserine, phosphatidylcholine and galactosylceramide (PubMed:23532839). Does not exhibit calcium-activated chloride channel (CaCC) activity (PubMed:23532839). May play a role in cell-cell interactions (By similarity). a 1,2-diacyl-sn-glycero-3-phospho-L-serine(in) = a 1,2-diacyl-sn-glycero-3-phospho-L-serine(out) a beta-D-galactosyl-(1<->1')-N-acylsphing-4-enine(out) = a beta-D-galactosyl-(1<->1')-N-acylsphing-4-enine(in) a 1,2-diacyl-sn-glycero-3-phosphocholine(in) = a 1,2-diacyl-sn-glycero-3-phosphocholine(out) Concentrates at sites of cell-cell contact. Shows an intracellular localization. Highly expressed in the stomach. Expressed at low levels in small intestine and large intestine. The term 'anoctamin' was coined because these channels are anion selective and have eight (OCT) transmembrane segments. There is some dissatisfaction in the field with the Ano nomenclature because it is not certain that all the members of this family are anion channels or have the 8-transmembrane topology. Belongs to the anoctamin family.
