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.
