Predicted to enable calcium channel activity. Predicted to contribute to cation channel activity and sour taste receptor activity. Predicted to be involved in several processes, including cellular response to acidic pH; detection of chemical stimulus involved in sensory perception of sour taste; and detection of mechanical stimulus. Predicted to be located in plasma membrane. Predicted to be part of cation channel complex and receptor complex. Predicted to be active in membrane. Predicted to colocalize with cell surface. Orthologous to human PKD1L3 (polycystin 1 like 3, transient receptor potential channel interacting). [provided by Alliance of Genome Resources, Apr 2022]
