WebJan 30, 2009 · The protein Tyr phosphatase (PTP) superfamily is distinguished by its CX 5 R catalytic signature motif shared by all of its members. It consists of the classical PTPs, the dual-specificity phosphatases (DSPs), the Cdc25 type phosphatases, and the low-molecular-weight phosphatases. WebMar 21, 2024 · Cdc25C is a dual specificity phosphatase essential for dephosphorylation and activation of cyclin-dependent kinase is a prerequisite step for mitosis in all eucaryotes. Cdc25C activation requires phosphorylation.

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
