B [auth I]	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
B [auth I]	PF16899	Cyclin C-terminal domain (Cyclin_C_2)	Cyclin C-terminal domain	Cyclins contain two domains of similar all-alpha fold, this family corresponds with the C-terminal domain of some cyclins including cyclin C and cyclin H [1].	Domain
