FUNCTION: Small-conductance calcium-activated nonselective cation (SCAN) channel which acts as a regulator of phospholipid scrambling in platelets and osteoblasts. Phospholipid scrambling results in surface exposure of phosphatidylserine which in platelets is essential to trigger the clotting system whereas in osteoblasts is essential for the deposition of hydroxyapatite during bone mineralization. Has calcium-dependent phospholipid scramblase activity; scrambles phosphatidylserine, phosphatidylcholine and galactosylceramide (By similarity). Can generate outwardly rectifying chloride channel currents in airway epithelial cells and Jurkat T lymphocytes. {ECO:0000250|UniProtKB:Q6P9J9, ECO:0000269|PubMed:20056604, ECO:0000269|PubMed:21107324, ECO:0000269|PubMed:21908539, ECO:0000269|PubMed:22006324, ECO:0000269|PubMed:22946059}.; FUNCTION: Upon SARS coronavirus-2/SARS-CoV-2 infection, is activated by spike protein which increases the amplitude of spontaneous Ca(2+) signals and is required for spike-mediated syncytia. {ECO:0000269|PubMed:33827113}.
