Anti-MEK6 (MKK6)

0.5mg/ml if reconstituted with 0.2ml sterile DI water. MAP2K6 (Mitogen-activated protein kinase kinase 6), also known as MAP kinase kinase 6 (MAPKK6 or MKK6) and MAPK/ERK kinase 6 (MEK6) is an enzyme that in humans is encoded by the MAP2K6 gene, on chromosome 17. MKK6 is a member of the dual specificity protein kinase family, which functions as a mitogen-activated protein (MAP) kinase kinase. Han et al.(1996) described experiments addressing the function of MKK6 in intracellular signaling pathways leading toward activation of p38 MAPK. Mukherjee et al.(2006) found that the Yersinia YopJ virulence factor acted as an acetyltransferase, using coenzyme A to modify critical ser and thr residues in the MKK6 activation loop, thereby blocking phosphorylation and kinase activation. They proposed that ser and/or thr acetylation by a bacterial effector may be a mechanism that occurs in other signaling pathways. Protein function: Dual specificity protein kinase which acts as an essential component of the MAP kinase signal transduction pathway. With MAP3K3/MKK3, catalyzes the concomitant phosphorylation of a threonine and a tyrosine residue in the MAP kinases p38 MAPK11, MAPK12, MAPK13 and MAPK14 and plays an important role in the regulation of cellular responses to cytokines and all kinds of stresses. Especially, MAP2K3/MKK3 and MAP2K6/MKK6 are both essential for the activation of MAPK11 and MAPK13 induced by environmental stress, whereas MAP2K6/MKK6 is the major MAPK11 activator in response to TNF. MAP2K6/MKK6 also phosphorylates and activates PAK6. The p38 MAP kinase signal transduction pathway leads to direct activation of transcription factors. Nuclear targets of p38 MAP kinase include the transcription factors ATF2 and ELK1. Within the p38 MAPK signal transduction pathway, MAP3K6/MKK6 mediates phosphorylation of STAT4 through MAPK14 activation, and is therefore required for STAT4 activation and STAT4- regulated gene expression in response to IL-12 stimulation. The pathway is also crucial for IL-6-induced SOCS3 expression and down-regulation of IL-6-mediated gene induction, and for IFNG-dependent gene transcription. Has a role in osteoclast differentiation through NF- kappa-B transactivation by TNFSF11, and in endochondral ossification and since SOX9 is another likely downstream target of the p38 MAPK pathway. MAP2K6/MKK6 mediates apoptotic cell death in thymocytes. Acts also as a regulator for melanocytes dendricity, through the modulation of Rho family GTPases. [The UniProt Consortium]
