Identification
HMDB Protein ID HMDBP07616
Secondary Accession Numbers
  • 13325
Name Cyclic nucleotide-gated cation channel alpha-4
Synonyms
  1. CNG channel alpha-4
  2. CNG-4
  3. CNG4
  4. Cyclic nucleotide-gated channel alpha-4
Gene Name CNGA4
Protein Type Unknown
Biological Properties
General Function Involved in ion channel activity
Specific 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
