Related Product Information for anti-MEKK3 antibody

MAP kinase kinase kinase (MEKK3 or MAP3K3) is a serine/threonine protein kinase that activates SAPK and ERK via phosphorylation and activation of their respective MAP kinase kinases, SEK and MEK1/2. MEKK3 also stimulates MEK5 via activation of ERK5/BMK1, which is at least partly regulated by a direct interaction between MEK5 and MEKK3 via p67phox-Bem1p (PB1) protein-protein interaction domains found in both proteins. MEKK3 modulates NF-kappaB activation in response to a variety of agonists including TNFalpha, LPS, IL-1 and LPA. Despite reports showing that phosphorylation of MEKK3 at Ser526 within the activation loop is necessary for kinase activation, at least one study suggests that dual phosphorylation at Thr516 and Ser520 is required for LPA-stimulated IKKbeta /NF-kappaB activation. Phosphorylation at Thr294 appears to negatively regulate MEKK3 by promoting 14-3-3beta binding and inhibition of the kinase activity.

NCBI Description

This gene product is a 626-amino acid polypeptide that is 96.5% identical to mouse Mekk3. Its catalytic domain is closely related to those of several other kinases, including mouse Mekk2, tobacco NPK, and yeast Ste11. Northern blot analysis revealed a 4.6-kb transcript that appears to be ubiquitously expressed. This protein directly regulates the stress-activated protein kinase (SAPK) and extracellular signal-regulated protein kinase (ERK) pathways by activating SEK and MEK1/2 respectively; it does not regulate the p38 pathway. In cotransfection assays, it enhanced transcription from a nuclear factor kappa-B (NFKB)-dependent reporter gene, consistent with a role in the SAPK pathway. Alternatively spliced transcript variants encoding distinct isoforms have been observed. [provided by RefSeq, Jul 2008]
