InnateDB Gene IDBG-28539 (CNGA4)
Protein Structure
UniProt Annotation
Function Second messenger, cAMP, causes the opening of cation- selective cyclic nucleotide-gated (CNG) channels and depolarization of the neuron (olfactory sensory neurons, OSNs). CNGA4 is the modulatory subunit of this channel which is known to play a central role in the transduction of odorant signals and subsequent adaptation. By accelerating the calcium-mediated negative feedback in olfactory signaling it allows rapid adaptation to odor stimulation and extends its range of odor detection (By similarity). {ECO:0000250}.
Subcellular Localization Membrane {ECO:0000305}; Multi-pass membrane protein {ECO:0000305}.
