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 WebMitogen-activated protein kinases (MAPKs) are serine and threonine protein kinases, highly conserved in eukaryotes, and are involved in signal transduction pathways that are related to modulation of physiological and …

DUSPs comprise the typical DUSPs, which contain a domain … WebJun 26, 2002 · MAP kinases are part of a three-tiered cascade consisting of a MAP kinase, a MAP kinase kinase (MAPKK, MKK or MEK) and a MAP kinase kinase kinase (MAPKKK or MEKK). Phosphorylation of the threonine and tyrosine residues in the T-loop of the MAP kinase, by its upstream kinase, results in activation.
WebApr 1, 2001 · Mitogen-activated protein (MAP) kinases comprise a family of ubiquitous proline-directed, protein-serine/threonine kinases, which participate in signal transduction pathways that control intracellular events including acute responses to hormones and major developmental changes in organisms. MAP kinases lie in protein kinase cascades. 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).
