FUNCTION: Component of a calcium channel. May act as a sour taste receptor by forming a calcium channel with PKD1L3 in gustatory cells; however, its contribution to sour taste perception is unclear in vivo and may be indirect. {ECO:0000269|PubMed:12782129, ECO:0000269|PubMed:19812697, ECO:0000269|Pu...
