C, F [auth G] | 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. | Domain |
C, F [auth G] | PF09080 | K cyclin, C terminal (K-cyclin_vir_C) | K cyclin, C terminal | Members of this family adopt a secondary structure consisting of a five alpha-helix cyclin fold. Interaction with cyclin dependent kinases (CDKs) at a PSTAIRE sequence motif within the catalytic cleft of CDK results in the regulation of CDK activity ... | Domain |
