Has calcium-dependent phospholipid scramblase activity; scrambles phosphatidylcholine and galactosylceramide (By similarity). Seems to act as potassium channel regulator and may inhibit pain signaling; can facilitate KCNT1/Slack channel activity by promoting its full single-channel conductance at very low sodium concentrations and by increasing its sodium sensitivity (By similarity). Does not exhibit calcium-activated chloride channel (CaCC) activity (PubMed:21984732). a 1,2-diacyl-sn-glycero-3-phosphocholine(in) = a 1,2-diacyl-sn-glycero-3-phosphocholine(out) a beta-D-galactosyl-(1<->1')-N-acylsphing-4-enine(out) = a beta-D-galactosyl-(1<->1')-N-acylsphing-4-enine(in) Interacts with KCNT1/Slack. Shows an intracellular localization. Highly expressed in the forebrain striatum. The disease is caused by variants affecting the gene represented in this entry. 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.
