Subdomain X of Cyclin-Dependent Kinase 2
Subdomain X includes residues 210-254. Although subdomain
X is not highly conserved within the kinase family, it is conserved within the
cyclin-dependent kinases. It contains the GDSEID motif at the N-terminal end
of the alpha-5 helix (helix G in cPKA.)
Between subdomains X and XI is a large insertion.
Currently, the importance of this region is unknown.
