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 | |
