cyclic nucleotide-gated channel alpha-1 isoform X1 [Homo sapiens]

Protein Classification

cyclic nucleotide-gated cation channel family protein( domain architecture ID 11998063)

cyclic nucleotide-gated cation channel family protein is a nonselective cation channel opened by binding of intracellular cyclic GMP or cyclic AMP, similar to human cGMP-gated cation channel alpha-1, a subunit of the rod cyclic GMP-gated cation channel which is involved in the final stage of the phototransduction pathway

 165-407 1.16e-37

Ion transport protein; This family contains sodium, potassium and calcium ion channels. This family is 6 transmembrane helices in which the last two helices flank a loop which determines ion selectivity. In some sub-families (e.g. Na channels) the domain is repeated four times, whereas in others (e.g. K channels) the protein forms as a tetramer in the membrane.

C-terminal leucine zipper domain of cyclic nucleotide-gated channels; The CLZ domain is the C-terminal leucine-zipper domain of of cyclic nucleotide-gated channel proteins. The CLZ domains form homotypic trimers in solution thus constraining the channel of the CNGs to contain three cyclic nucleotide-gated subunits, CNGA. The CLZ domains formed homotypic parallel 3-helix coiled-coil domains, consistent with their proposed role in regulating subunit assembly.

effector domain of the CAP family of transcription factors; members include CAP (or cAMP receptor protein (CRP)), which binds cAMP, FNR (fumarate and nitrate reduction), which uses an iron-sulfur cluster to sense oxygen) and CooA, a heme containing CO sensor. In all cases binding of the effector leads to conformational changes and the ability to activate transcription. Cyclic nucleotide-binding domain similar to CAP are also present in cAMP- and cGMP-dependent protein kinases (cAPK and cGPK) and vertebrate cyclic nucleotide-gated ion-channels. Cyclic nucleotide-monophosphate binding domain; proteins that bind cyclic nucleotides (cAMP or cGMP) share a structural domain of about 120 residues; the best studied is the prokaryotic catabolite gene activator, CAP, where such a domain is known to be composed of three alpha-helices and a distinctive eight-stranded, antiparallel beta-barrel structure; three conserved glycine residues are thought to be essential for maintenance of the structural integrity of the beta-barrel; CooA is a homodimeric transcription factor that belongs to CAP family; cAMP- and cGMP-dependent protein kinases (cAPK and cGPK) contain two tandem copies of the cyclic nucleotide-binding domain; cAPK's are composed of two different subunits, a catalytic chain and a regulatory chain, which contains both copies of the domain; cGPK's are single chain enzymes that include the two copies of the domain in their N-terminal section; also found in vertebrate cyclic nucleotide-gated ion-channels

Ion transport protein; This family contains sodium, potassium and calcium ion channels. This family is 6 transmembrane helices in which the last two helices flank a loop which determines ion selectivity. In some sub-families (e.g. Na channels) the domain is repeated four times, whereas in others (e.g. K channels) the protein forms as a tetramer in the membrane.

C-terminal leucine zipper domain of cyclic nucleotide-gated channels; The CLZ domain is the C-terminal leucine-zipper domain of of cyclic nucleotide-gated channel proteins. The CLZ domains form homotypic trimers in solution thus constraining the channel of the CNGs to contain three cyclic nucleotide-gated subunits, CNGA. The CLZ domains formed homotypic parallel 3-helix coiled-coil domains, consistent with their proposed role in regulating subunit assembly.

 479-595 6.01e-24

effector domain of the CAP family of transcription factors; members include CAP (or cAMP receptor protein (CRP)), which binds cAMP, FNR (fumarate and nitrate reduction), which uses an iron-sulfur cluster to sense oxygen) and CooA, a heme containing CO sensor. In all cases binding of the effector leads to conformational changes and the ability to activate transcription. Cyclic nucleotide-binding domain similar to CAP are also present in cAMP- and cGMP-dependent protein kinases (cAPK and cGPK) and vertebrate cyclic nucleotide-gated ion-channels. Cyclic nucleotide-monophosphate binding domain; proteins that bind cyclic nucleotides (cAMP or cGMP) share a structural domain of about 120 residues; the best studied is the prokaryotic catabolite gene activator, CAP, where such a domain is known to be composed of three alpha-helices and a distinctive eight-stranded, antiparallel beta-barrel structure; three conserved glycine residues are thought to be essential for maintenance of the structural integrity of the beta-barrel; CooA is a homodimeric transcription factor that belongs to CAP family; cAMP- and cGMP-dependent protein kinases (cAPK and cGPK) contain two tandem copies of the cyclic nucleotide-binding domain; cAPK's are composed of two different subunits, a catalytic chain and a regulatory chain, which contains both copies of the domain; cGPK's are single chain enzymes that include the two copies of the domain in their N-terminal section; also found in vertebrate cyclic nucleotide-gated ion-channels
