Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables several functions, including calcium ion binding activity; identical protein binding activity; and transmembrane transporter binding activity. Contributes to monoatomic cation channel 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. Located in endoplasmic reticulum and plasma membrane. Part of calcium channel complex and receptor complex. Colocalizes with cell surface. Is expressed in cochlea; medulla oblongata; spinal cord; and tongue. Orthologous to human PKD2L1 (polycystin 2 like 1, transient receptor potential cation channel).
