Previous GeneCards Identifiers for CDC25B Gene
CDC25B is a member of the CDC25 family of phosphatases. CDC25B activates the cyclin dependent kinase CDC2 by removing two phosphate groups and it is required for entry into mitosis. CDC25B shuttles between the nucleus and the cytoplasm due to nuclear localization and nuclear export signals. The protein is nuclear in the M and G1 phases of the cell cycle and moves to the cytoplasm during S and G2. CDC25B has oncogenic properties, although its role in tumor formation has not been determined. Multiple transcript variants for this gene exist. [provided by RefSeq, Jul 2008]
GeneCards Summary for CDC25B Gene
CDC25B (Cell Division Cycle 25B) is a Protein Coding gene. Diseases associated with CDC25B include Esophageal Cancer. Among its related pathways are Aurora A signaling and Regulation of PLK1 Activity at G2/M Transition. GO annotations related to this gene include protein kinase binding and protein tyrosine phosphatase activity. An important paralog of this gene is CDC25A.
UniProtKB/Swiss-Prot for CDC25B Gene
Tyrosine protein phosphatase which functions as a dosage-dependent inducer of mitotic progression. Required for G2/M phases of the cell cycle progression and abscission during cytokinesis in a ECT2-dependent manner. Directly dephosphorylates CDK1 and stimulates its kinase activity. The three isoforms seem to have a different level of activity.
Cdc25 is a dual specificity phosphatase with three isoforms in mammalian cells - Cdc25A, B and C. Cdc25 activates cdk complexes that drive the cell cycle. Cdc25 is involved in the DNA damage checkpoints and is known as a key mediator of cell cycle progression.
