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 regulated tightly, but the changes in expression patterns in cancer cells that lead to tumorigenesis are unknown. In this study, we showed that ubiquitin-specific protease 29 …

At the end of the cycle, all of the negative regulators are turned back on, Cdc13/Cdc2 kinase activity is lost, and the cell leaves mitosis. The mechanism of activation of the negative regulators is largely ...
WebCdc25 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 … WebThe phosphorylation of Cdc25 phosphatase by CDK presents a mutual activation as both enzymes “help” each other: CDK activates its phosphatase Cdc25 which in return removes the inhibitory phosphate groups from CDK. This is remarkably a different type of positive feedback regulation than the CDK-Wee1 link (Fig. 2).
WebCDC25, dual specificity phosphatase (DSP), is an important checkpoint component, and dysregulation of CDC25 can contribute to genomic instability. Genomic instability occurs when cell continues to divide and the DNA lesion is passed to daughter cells due to defective cell cycle checkpoint. WebBy database analysis, Vasudevan et al. (2005) identified human DUSP26, which they called MKP8. The deduced 211-amino acid protein has a 131-amino acid DSP catalytic domain. MKP8 shares closest homology with DUSP3 and DUSP13 (), but it lacks significant homology with CDC25 proteins (see 116947).Human MKP8 shares over 90% sequence …
WebMay 4, 2007 · The Cdc25 family of phosphatases is responsible for dephosphorylating inhibitory Tyr and Thr residues on cyclin-dependent kinases in order to promote their activation. Three isoforms (A, B and C) have been identified in mammals while only two isoforms (A and C) have been characterized in Xenopus.
WebCDC25A is a member of the CDC25 family of dual-specificity phosphatases . Dual-specificity protein phosphatases remove phosphate groups from phosphorylated tyrosine and serine / threonine residues.
