Predicted to enable several functions, including cation channel activity; identical protein binding activity; and muscle alpha-actinin binding activity. Predicted to contribute to cation channel activity and sour taste receptor activity. Predicted to be involved in several processes, including detection of chemical stimulus involved in sensory perception of sour taste; inorganic cation transmembrane transport; and protein homotetramerization. Predicted to be located in endoplasmic reticulum; non-motile cilium; and plasma membrane. Predicted to be integral component of plasma membrane. Predicted to be part of calcium channel complex and receptor complex. Predicted to be active in membrane. Predicted to colocalize with cell surface. Orthologous to human PKD2L1 (polycystin 2 like 1, transient receptor potential cation channel). [provided by Alliance of Genome Resources, Apr 2022]
