      Background InformationCyclins are, as their name suggests, expressed at specific times during the cell cycle, and play a crucial role in the regulation of the cell cycle. Cyclins associate with cyclin-dependent kinases (cdks), and the association is absolutely required for cdk activity. At the conclusion of the relevant phase of the cell cycle, cyclins are rapidly ubiquitinated and degraded, thus returning cdks to their inactive state. Cyclin A associates with cdk2, and together with cyclin E is involved in the G1/S transition. Cyclin A/cdk2 remains active during S-phase. Cyclin B associates with cdk1/cdc2 to regulate the G2/M boundary. The D-cyclins bind cdk4 and cdk6, and result in Rb phosphorylation. The cyclin D1 gene was found in chronic B cell lymphocytic leukemia, and designated Bcl-1, though that nomenclature is no longer used.

      Entrez Gene Number
      Entrez Gene SummaryThe 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 cycle. Cyclins function as regulators of CDK kinases. Different cyclins exhibit distinct expression and degradation patterns which contribute to the temporal coordination of each mitotic event. This cyclin forms a complex with and functions as a regulatory subunit of CDK2. This cyclin has been shown to specifically interact with CIP/KIP family of CDK inhibitors, and plays a role in cell cycle G1/S transition. The expression of this gene peaks at the G1-S phase and exhibits a pattern of tissue specificity distinct from that of cyclin E1. A significantly increased expression level of this gene was observed in tumor-derived cells. [provided by RefSeq]

      • CYCE2
      UniProt Number
      UniProt SummaryFunction: 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.
