Identification
HMDB Protein ID CDBP03332
Secondary Accession Numbers Not Available
Name Cyclic nucleotide-gated olfactory channel
Description Not Available
Synonyms
  1. CNG channel alpha-2
  2. CNG-2
  3. CNG2
  4. Cyclic nucleotide-gated cation channel 2
  5. Cyclic nucleotide-gated channel alpha-2
Gene Name CNGA2
Protein Type Transporter
Biological Properties
General Function Involved in ion channel activity
Specific Function Odorant signal transduction is probably mediated by a G- protein coupled cascade using cAMP as second messenger. The olfactory channel can be shown to be activated by cyclic nucleotides which leads to a depolarization of olfactory sensory neurons
