Claim: Cyclin A1 belongs to the highly conserved cyclin family and functions as activating subunits of enzymatic complex together with cyclin-dependent kinases (CDKs), the families of protein kinases.
Evidence: The protein encoded by this gene belongs to the highly conserved cyclin family, whose members are characterized by a dramatic periodicity in protein abundance through the cell division cycle. Cyclins function as activating subunits of enzymatic complex together with cyclin-dependent kinases (CDKs). Cyclin-dependent kinases (CDKs) are the families of protein kinases first discovered for their role in regulating the cell cycle.
