Cnga2 - cyclic nucleotide gated channel subunit alpha 2

Enables cGMP binding activity; identical protein binding activity; and intracellular cyclic nucleotide activated cation channel activity. Involved in membrane depolarization and sensory perception of smell. Located in perikaryon and plasma membrane. Part of intracellular cyclic nucleotide activated cation channel complex. Orthologous to human CNGA2 (cyclic nucleotide gated channel subunit alpha 2). [provided by Alliance of Genome Resources, Apr 2022]
