Dusps to map kinases and beyond
WebAbstract The protein tyrosine phosphatase family (PTP) contains a group of dual-specificity phosphatases (DUSPs) that regulate the activivity of MAP kinases (MAPKs), which are … WebThe MAPK pathway is composed of (i) MAP kinase kinase kinase (MAP3K), (ii) MAP kinase kinase (MAP2K), and (iii) MAPK. Dual phosphorylation of Tyr and Thr residues at the activation loop activates MAPKs, and inactivation is mediated by several phosphatases.

WebThe activity of MAP kinases are tightly controlled by a family of dual-specificity MAP kinase phosphatases (DUSPs) and they have been shown to have a variety of physiological and pathological roles (Liu and Molkentin, 2016). 10 DUSP transcripts were significantly up or downregulated in HF (data not shown). Many molecular mechanisms responsible for the cross-regulations between DUSPs and MAP kinases have been discussed (summarized in Figure 4). However, the possibility that typical DUSPs may dephosphorylate non-MAP kinase proteins must also be considered. During our characterization of DUSP4 … See more The dual-specificity phosphatase (DUSP) family proteins are so named for their ability to dephosphorylate both the threonine/serine and tyrosine residues of their substrates. This … See more DUSPs’ primary mode of action is the dephosphorylation of tyrosine and/or serine/threonine residues and the resulting activity regulation of their substrates. The physiological outcomes of DUSPs’ functions thus hinge … See more Signals from the MAP kinases are important for thymocyte development and helper T cell polarization (reviewed in [4]). In addition, several DUSPs have been found to be … See more
