The name of this superfamily has been modified since the most recent official CATH+ release (v4_2_0). At the point of the last release, this superfamily was named:

"
Winged helix-like DNA-binding domain superfamily/Winged helix DNA-binding domain
".

FunFam 265627: Rap guanine nucleotide exchange factor 4

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
CGMP-dependent protein kinase. [EC: 2.7.11.12]
ATP + a protein = ADP + a phosphoprotein.
  • cGMP is required to activate this enzyme.
  • The enzyme occurs as a dimer in higher eukaryotes.
  • The C-terminal region of each polypeptide chain contains the catalytic domain that includes the ATP and protein substrate binding sites.
  • This domain catalyzes the phosphorylation by ATP to specific serine or threonine residues in protein substrates.
  • The enzyme also has two allosteric cGMP-binding sites (sites A and B).
  • Binding of cGMP causes a conformational change that is associated with activation of the kinase.
  • Formerly EC 2.7.1.37.
