General annotation (Comments)

Function

Essential for the control of the cell cycle at the late G1 and early S phase.

Subunit structure

Interacts with the CDK2 (in vivo) and CDK3 (in vitro) protein kinases to form a serine/threonine kinase holoenzyme complex. The cyclin subunit imparts substrate specificity to the complex.

Subcellular location

Nucleus. Ref.3

Tissue specificity

According to Ref.1: highest levels in adult testis, thymus and brain. Lower levels in placenta, spleen and colon. Consistently elevated levels in tumor-derived cells compared to non-transformed proliferating cells. According to Ref.2: low levels in thymus, prostate, brain, skeletal muscle, and kidney. Elevated levels in lung. According to Ref.3: highly expressed in testis, placenta, thymus and brain. In a lesser extent in small intestine and colon.

Induction

Activated by papilloma viral oncoproteins E6 and E7 which bind to and inactivate p53 and Rb, respectively.

Post-translational modification

Phosphorylation by CDK2 triggers its release from CDK2 and degradation via the ubiquitin proteasome pathway By similarity.

Sequence similarities

Belongs to the cyclin family. Cyclin E subfamily.
