WebJun 4, 2012 · Cyclin-dependent kinase 1 (Cdk1) kinase dephosphorylation and activation by Cdc25 phosphatase are essential for mitotic entry. Activated Cdk1 phosphorylates Cdc25 and other substrates, further activating Cdc25 to form a positive feedback loop that drives the abrupt G2/mitosis switch.

WebCell division cycle 25A (Cdc25A) is a dual-specificity phosphatase that is overexpressed in several cancer cells and promotes tumorigenesis. In normal cells, Cdc25A expression is … WebIzumi, T. and Maller, J. L. (1993) Elimination of cdc2 phosphorylation sites in the cdc25 phosphatase blocks initiation of M-phase. Mol. Biol. Cell 4, 1337–1350. Izumi, T. and Maller, J. L. (1995) Phosphorylation and acitvation of the Xenopus cdc25 phosphatase in the absence of cdc2 and cdk2 kinase activity. Mol. Biol. Cell 6, 215–226. Cdc25 activates cyclin dependent kinases by removing phosphate from residues in the Cdk active site. In turn, the phosphorylation by M-Cdk (a complex of Cdk1 and cyclin B) activates Cdc25. Together with Wee1, M-Cdk activation is switch-like. The switch-like behavior forces entry into mitosis to be quick and … See more The structure of Cdc25 proteins can be divided into two main regions: the N-terminal region, which is highly divergent and contains sites for its phosphorylation and ubiquitination, which regulate the phosphatase activity; … See more The Cdc25s, and in particular Cdc25A and Cdc25B, are proto-oncogenes in humans and have been shown to be overexpressed in a number of cancers. The central role of Cdc25s in the cell cycle has garnered them considerable attention … See more Cdc25 enzymes are well conserved through evolution, and have been isolated from fungi such as yeasts as well as all metazoans examined … See more Although the highly conserved nature of the Cdc25s implies an important role in cell physiology, Cdc25B and Cdc25C knockout mice (both … See more ghost hunt anime news network
