   cyclic nucleotide-gated channel alpha subunit
 |
   CATSPERB
 |
  "A cyclic nucleotide-regulated channel protein that has amino- and carboxyl-terminal intracellular domains separated by a domain (common with other ion channels) containing six transmembrane helices (S1-S6) in which the last two helices (S5 and S6) flank a loop, called the pore loop, which determines ion selectivity. The carboxy-terminal region contains the Cyclic nucleotide-binding domain (Pfam:PF00027) (CNBD) and a region connecting the CNBD to the S6 segment (C-linker), which is important for modulation by transition metals. In addition, CNG alpha has a carboxy-terminal leucine zipper that seems to be involved in inter-subunit interaction. CNG alpha subunits combine with the beta subunits to form the cyclic nucleotide-gated ion channels, which mediate sensory transduction in photoreceptors and olfactory sensory neurons. These channels are likely composed of four subunits around a centrally located ion-permeable pore that opens in response to the direct binding of intracellular cyclic nucleotides. CNG channels are non-selective cation channels. They are not gated by membrane voltage although their structure includes the transmembrane S4 motif known to function as the membrane voltage sensor in all voltage-gated ion channels, but it has been shown to be important for proper folding and processing. Alpha and beta subunits of the CNG channel are very similar, however only alpha subunits are able to homooligomerize and form functional channels." [PMID:12432397, PRO:CNA]

   cyclic nucleotide-gated channel beta subunit
 |
   CATSPERB
 |
  "A cyclic nucleotide-regulated channel protein that is the modulatory subunit of the cyclic nucleotide-gated channel (CNG channel). It consists of amino- and carboxyl-terminal intracellular domains separated by a domain (common with other ion channels) containing six transmembrane helices (S1-S6) in which the last two helices (S5 and S6) flank a loop, called the pore loop, which determines ion selectivity. The carboxy-terminal region contains the Cyclic nucleotide-binding domain (Pfam:PF00027) (CNBD) and a region connecting the CNBD to the S6 segment (C-linker), which is important for modulation by transition metals. CNG beta subunits combine with the alpha subunits to form the cyclic nucleotide-gated ion channels, which mediate sensory transduction in photoreceptors and olfactory sensory neurons. These channels are likely composed of four subunits around a centrally located ion-permeable pore that opens in response to the direct binding of intracellular cyclic nucleotides. CNG channels are non-selective cation channels. They are not gated by membrane voltage although their structure includes the transmembrane S4 motif known to function as the membrane voltage sensor in all voltage-gated ion channels, but it has been shown to be important for proper folding and processing. Alpha and beta subunits of the CNG channel are very similar, however the beta subunits are not able to form functional channels by themselves." [PRO:CNA]

  "A cyclic nucleotide-regulated channel protein that has amino- and carboxyl-terminal intracellular domains separated by a domain (common with other ion channels) containing six transmembrane helices (S1-S6) in which the last two helices (S5 and S6) flank a loop, called the pore loop, which determines ion selectivity. The N terminus has a conserved domain that is also present in other voltage-gated potassium and sodium channels. The carboxyl-terminal region contains the cyclic nucleotide-binding domain (CNBD). In addition, there is a structural element called the C-linker, the region connecting the CNBD to the S6 segment, which couples conformational changes in the ligand-binding domain to channel activation. Subunits combine to form the HCN channels. In common with CNG channels, HCN are cation channels that are modulated by cyclic nucleotide binding. Unlike CNG channels, HCN channels are voltage-gated, and are weakly selective for potassium. In contrast to most other voltage-gated channels, HCN channels open upon hyperpolarization and close at positive potential. HCN channels act as a pacemaker by regulating neuronal and cardiac firing rate, but also function as a regulator of membrane resting potential and resistance." [PMID:16382102]
