Automated description from the Alliance of Genome Resources
Exhibits calcium channel activity; calcium ion binding activity; and identical protein binding activity. Contributes to cation transmembrane transporter activity and sour taste receptor activity. Involved in several processes, including cellular response to acidic pH; detection of chemical stimulus involved in sensory perception of sour taste; and protein tetramerization. Localizes to several cellular components, including the calcium channel complex; endoplasmic reticulum; and integral component of plasma membrane. Colocalizes with the cell surface. Is expressed in circumvallate papilla; cochlea; intermediate grey horn; medulla oblongata; and spinal cord. Orthologous to human PKD2L1 (polycystin 2 like 1, transient receptor potential cation channel).
