CyclinsRegulatory proteins that function in the cell cycle to activate maturation promoting factor. They complex with p34cdc2 (PROTEIN P34CDC2), the catalytic subunit of MATURATION-PROMOTING FACTOR, and modulate its protein kinase activity. Cyclins themselves have no enzymatic activity.
ProteinsLinear POLYPEPTIDES that are synthesized on RIBOSOMES and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of AMINO ACIDS determines the shape the polypeptide will take, during PROTEIN FOLDING, and the function of the protein.
