Enables stretch-activated, monoatomic cation-selective, calcium channel activity. Involved in cellular response to cold; detection of mechanical stimulus involved in sensory perception of touch; and detection of temperature stimulus involved in thermoception. Predicted to be active in membrane. Is expressed in antennal lobe glomerulus VP3; aristal sensory neuron VP3; sacculus; and second segment of antenna. Orthologous to human PKD1L3 (polycystin 1 like 3, transient receptor potential channel interacting).
