Gene: CNGA2 (cyclic nucleotide gated channel subunit alpha 2) Homo sapiens
Symbol: CNGA2
Name: cyclic nucleotide gated channel subunit alpha 2
Description: The protein encoded by this gene represents the alpha subunit of a cyclic nucleotide-gated olfactory channel. The encoded protein contains a carboxy-terminal leucine zipper that mediates channel formation. [provided by RefSeq, Jan 2010]
Type: protein-coding
RefSeq Status: REVIEWED
