Dual specificity phosphatase 1

MKP-1, VH1, VHI, MAP kinase phosphatase-1, DUSP1
The expression of DUSP1 gene is induced in human skin fibroblasts by oxidative/heat stress and growth factors. It specifies a protein with structural features similar to members of the non-receptor-type protein-tyrosine phosphatase family, and which has significant amino-acid sequence similarity to a Tyr/Ser-protein phosphatase encoded by the late gene H1 of vaccinia virus. The bacterially expressed and purified DUSP1 protein has intrinsic phosphatase activity, and specifically inactivates mitogen-activated protein (MAP) kinase in vitro by the concomitant dephosphorylation of both its phosphothreonine and phosphotyrosine residues. Furthermore, it suppresses the activation of MAP kinase by oncogenic ras in extracts of Xenopus oocytes. Thus, DUSP1 may play an important role in the human cellular response to environmental stress as well as in the negative regulation of cellular proliferation.

New
Johnson et al., Nanjing, China. In Mol Endocrinol, 17 Sep 2015
We now report that P4 also acts via GR to induce mitogen-activated protein (MAP) kinase phosphatase-1 (MKP-1) and knockdown of MKP-1 impairs the ability of P4 to repress IL-1β-dependent COX-2 induction.

New
Jasmin et al., Ottawa, Canada. In J Neurosci, 05 Sep 2015
Finally, p38 MAPK, a pathway known to activate HuR, was induced following denervation as a result of MKK3/6 activation and a decrease in MKP-1 expression, thereby leading to an increase in the stability of AChR β-subunit transcripts.

Activation of AMPKα2 in adipocytes is essential for nicotine-induced insulin resistance in vivo.
New
Impact
Zou et al., Oklahoma City, United States. In Nat Med, Apr 2015
Here we show that nicotine, a major constituent of cigarette smoke, selectively activates AMP-activated protein kinase α2 (AMPKα2) in adipocytes, which in turn phosphorylates MAP kinase phosphatase-1 (MKP1) at serine 334, initiating its proteasome-dependent degradation.

Our previous work identified a critical role for mitogen-activated protein kinase (MAPK) phosphatase-1 (MKP-1) in mediating the anti-proliferative effects of GCs in immortalized pre-osteoblasts, but we subsequently found that MKP-1 null mice were not protected against the pathological effects of GCs on bone.
