Enables calcium activated cation channel activity; potassium channel activity; and sodium channel activity. Acts upstream of or within ion transmembrane transport. Predicted to be located in dendrite and neuronal cell body. Predicted to be integral component of membrane. Predicted to be integral component of plasma membrane. Is expressed in several structures, including ganglia; genitourinary system; gut; hemolymphoid system gland; and liver and biliary system.
