- Cdk1
Cell division cycle 2, G1 to S and G2 to M, also known as Cdk1 (CDC2), is a human
gene . The protein encoded by this gene is called p34cdk1 and is acyclin-dependent kinase in the Ser/Thr protein kinase family. This protein is a catalytic subunit of the highly conserved protein kinase complex known asmaturation promoting factor (MPF), which is essential for G1/S and G2/M phase transitions of eukaryotic cell cycle. Mitoticcyclin s stably associate with this protein and function as regulatory subunits. The kinase activity of this protein is controlled by cyclin accumulation and destruction through the cell cycle. The phosphorylation and dephosphorylation of this protein also play important regulatory roles in cell cycle control. [cite web | title = Entrez Gene: Cdk1 cell division cycle 2, G1 to S and G2 to M| url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=983| accessdate = ]Cdk1 is one of the components of the
maturation promoting factor (MPF) which controls thecell division cycle in yeast. Cdk1 is a cyclin-dependent kinase (CDK) which, when bound tocyclin B , allows a dividing cell to enter intomitosis fromG2 (in the absence of inhibitory proteins such asWee1 ). Cdk1 also permits the transition from G1 through S in conjunction withcyclin A andcyclin E .

Cell Biol. |volume=7 |issue=8 |pages=831–6 |year=2005 |month=Aug |pmid=16007079 |doi=10.1038/ncb1284 |url=]In humans, the functions of cdc2 are divided between its homologues. Some important ones are Cdk1, Cdk2, Cdk4, and Cdk6 (See
cyclin-dependent kinase ), which associate with different cyclins and regulate stage transitions during the cell cycle.Other "Cell division cycle" genes (cdc's) are also involved in complex regulatory pathways during the cell cycle. Cdc's were originally discovered in "
Saccharomyces cerevisiae ", and are followed by a number which signifies the order in which they were discovered (e.g. cdc2,cdc20 ,cdc25 , etc).References
