WebNov 3, 2003 · Similar results were obtained using GST–Cdc25 (1–322) lacking the Cdc25 phosphatase domain or endogenous Cdc25 immunoprecipitated from an interphase extract as substrates (data not shown). As recently reported, Chk1/Cds1 cannot re-phosphorylate this site once it is dephosphorylated due to Cdc2-induced phosphorylation at S285 on … Web5.2.1 The Cdc25 Phosphatases Three members of the Cdc25 gene family are described in mammals: Cdc25A, B, and C. These genes encode highly similar dual-specificity phosphatases which are able to dephosphorylate both phospho-threonine and -tyrosine residues (Dunphy & Kumagai, 1991 ).

WebThe fungal meningitis pathogen Cryptococcus neoformans is a central driver of mortality in HIV/AIDS. We report a genome-scale chemical genetic data map for this pathogen that quantifies the impact of 439 small-molecule challenges on 1,448 gene knockouts. We identified chemical phenotypes for 83% of mutants screened and at least one genetic ... 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.
WebCell Division Cycle-25 (CDC25) plays an important role in transitions between cell-cycle phases by dephosphorylating and activating CDKs. CDC25B and CDC25C play a major role in G2/M progression, whereas CDC25A assists in G1/S transition. Different isomers of CDC25 expressions are upregulated in various clinicopathological situations. 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).
