Function

[MP2K6_HUMAN] 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.^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7] ^[8]

Publication Abstract from PubMed

Mitogen-activated protein kinase kinase 6 (MAP2K6) plays a crucial role in the p38 MAP kinase signal cascade that regulates various stress-induced responses and is associated with pathological conditions. The crystal structure of human non-phosphorylated MAP2K6 (npMAP2K6) complexed with an ATP analogue was determined at 2.6 A resolution and represents an auto-inhibition state of MAP2K6. Three characteristics of short alpha-helices configured in the activation loop region, termed activation helices (AH1, AH2 and AH3), are important in controlling the auto-inhibition mechanism. AH1 displaces the alphaC-helix, a component essential for forming the active configuration, away from the active site. AH1 and AH2 were found to enclose the gamma-phosphate, the leaving group of ATP. A comparison with the related enzymes, MAP2K1 and MAP2K4 reveals that MAP2K6 has the unique auto-inhibition mechanism mediated by the three activation helices.
