TAK1-TAB1 Kinase Assay Kit
The TAK1-TAB1 Kinase Assay Kit is designed to measure TAK1-TAB1 kinase activity for screening and profiling applications using ADP-Glo® Kinase Assay as a detection reagent.
MBP (Myelin Basic Protein) is a non-specific protein substrate that is used as a "universal substrate" for many in-vitro kinase activity assays. This protein is targeted by many serine/threonine kinases at conserved amino acids. We use the dephosphorylated version of the MBP substrate in our assays to determine the kinase-mediated phosphorylation of MBP. Our assays are not suitable for studying autophosphorylation of the kinase due to the presence of the MBP substrate.

TAK1 is a serine/threonine protein kinase that mediates signaling by TGFβ and morphogenetic protein (BMP). In response to IL-1, TAK1 forms a kinase complex with TAB1 and this complex is required for the activation of nuclear factor kappa B (NF-κB). TAK1 can also activate MAPK8/JNK and MAP2K4/MKK4 and thus play a role in the cell response to environmental stress. It has been implicated in various inflammation disorders and cancers, including breast and pancreatic cancer.
