WebPhosphatase and tensin homolog (PTEN) is a tumor suppressor phosphatase negative regulator of the P13K/Akt pathway (Maehama & Dixon, 1998; Myers et al., 1997 ). SNO … 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

WebMar 21, 2024 · CDC25A is a member of the CDC25 family of phosphatases. CDC25A is required for progression from G1 to the S phase of the cell cycle. It activates the cyclin-dependent kinase CDC2 by removing two phosphate groups. CDC25A is specifically degraded in response to DNA damage, which prevents cells with chromosomal … WebCdc25 is a dual specificity phosphatase with three isoforms in mammalian cells - Cdc25A, B and C.
