CDK1 Antibody – Mouse Monoclonal

The protein encoded by this gene is a member of the Ser/Thr protein kinase family. This protein is a catalytic subunit of the highly conserved protein kinase complex known as M-phase promoting factor (MPF), which is essential for G1/S and G2/M phase transitions of eukaryotic cell cycle. Mitotic cyclins 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. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]

CDK1: a protein kinase of the CDK family. Catalytic subunit of the conserved protein complex known as M-phase promoting factor (MPF), which is essential for G1/S and G2/M phase transitions. Mitotic cyclins stably associate with this protein and function as regulatory subunits. Its activity is controlled by cyclin availability and phosphorylation through the cell cycle. Activated in many cancers including colon, liver and breast. The T isoform, which lacks a regulatory region, is expressed in breast cancer. Inhibition in cancer cells may drive cells into apoptosis. May also drive cell migration. Inhibitors: BMS-265246, BMS-265246-01. 2 isoforms of the human protein are produced by alternative splicing.
