A	PF09241	Herpesviridae viral cyclin (Herp-Cyclin)	Herpesviridae viral cyclin	Members of this family of viral cyclins adopt a helical structure consisting of five alpha-helices, with one helix surrounded by the others. They specifically activate CDK6 of host cells to a very high degree [1].	Domain
A	PF00134	Cyclin, N-terminal domain (Cyclin_N)	Cyclin, N-terminal domain	Cyclins regulate cyclin dependent kinases (CDKs). Swiss:P22674 is a Uracil-DNA glycosylase that is related to other cyclins [4]. Cyclins contain two domains of similar all-alpha fold, of which this family corresponds with the N-terminal domain.
