Enables calcium activated cation channel activity. Predicted to be involved in several processes, including metal ion transport; positive regulation of cardiac muscle hypertrophy in response to stress; and response to ATP. Predicted to be integral component of membrane. Predicted to be part of cation channel complex. Predicted to be integral component of plasma membrane. Human ortholog(s) of this gene implicated in cerebellar ataxia type 41. Orthologous to human TRPC3 (transient receptor potential cation channel subfamily C member 3).
