Bos taurus (Bovine)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Cyclin which controls both the G1/S and the G2/M transition phases of the cell cycle. Functions through the formation of specific serine/threonine kinase holoenzyme complexes with the cyclin-dependent protein kinases CDK1 and CDK2. The cyclin subunit confers the substrate specificity of these complexes and differentially interacts with and activates CDK1 and CDK2 throughout the cell cycle.By similarity

Interactioni

Subunit structurei

Interacts with the CDK1 and CDK2 protein kinases to form serine/threonine kinase holoenzyme complexes. Interacts with CDK1 (hyperphosphorylated form in G1 and underphosphorylated forms in S and G2). Interacts with CDK2; the interaction increases from G1 to G2. Interacts (associated with CDK2 but not with CDK1) with SCAPER; regulates the activity of CCNA2/CDK2 by transiently maintaining CCNA2 in the cytoplasm. Forms a ternary complex with CDK2 and CDKN1B; CDKN1B inhibits the kinase activity of CDK2 through conformational rearrangements.By similarity

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
