Protein Structure

UniProt Annotation

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:0000269PubMed:16805797, ECO:0000269PubMed:16891422, ECO:0000269PubMed:16929298, ECO:0000269PubMed:21098668, ECO:0000269PubMed:21625513}.

Subcellular Localization

Cell membrane {ECO:0000269PubMed:16891422, ECO:0000269PubMed:21185261}; Multi-pass membrane protein {ECO:0000269PubMed:16891422, ECO:0000269PubMed:21185261}. Note=Interaction with PKD2L1 is required for localization to the cell membrane.

Disease Associations

Tissue Specificity

Expressed in a subset of taste receptor cells distinct from those involved in bitter, sweet and umami taste. Expressed in circumvallate and foliate taste buds, but not in surrounding non-gustatory lingual epithelium cells. Expressed in testis. {ECO:0000269PubMed:16805797, ECO:0000269PubMed:16891422, ECO:0000269PubMed:16929298}.
