pfam16526: CLZ (This model is not part of the current CDD release)
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.
