Overview 
Serine/threonine kinase which acts as an essential component of the MAP kinase signal transduction pathway. Plays an important role in the cascades of cellular responses evoked by changes in the environment. Mediates signal transduction of TRAF6, various cytokines including interleukin-1 (IL-1), transforming growth factor-beta (TGFB), TGFB-related factors like BMP2 and BMP4, toll-like receptors (TLR), tumor necrosis factor receptor CD40 and B-cell receptor (BCR). Ceramides are also able to activate MAP3K7/TAK1. Once activated, acts as an upstream activator of the MKK/JNK signal transduction cascade and the p38 MAPK signal transduction cascade through the phosphorylation and activation of several MAP kinase kinases like MAP2K1/MEK1, MAP2K3/MKK3, MAP2K6/MKK6 and MAP2K7/MKK7. These MAP2Ks in turn activate p38 MAPKs, c-jun N-terminal kinases (JNKs) and I-kappa-B kinase complex (IKK). Both p38 MAPK and JNK pathways control the transcription factors activator protein-1 (AP-1), while nuclear factor-kappa B is activated by IKK. MAP3K7 activates also IKBKB and MAPK8/JNK1 in response to TRAF6 signaling and mediates BMP2-induced apoptosis. In osmotic stress signaling, plays a major role in the activation of MAPK8/JNK1, but not that of NF-kappa-B. Promotes TRIM5 capsid-specific restriction activity.

Enzymatic activity 
This protein acts as an enzyme. It is known to catalyze the following reaction
EC 2.7.11.25: ATP + a protein ADP + a phosphoprotein.  
  • CuratedUniProtKB
It requires the following cofactor
Magnesium.  
  • CuratedUniProtKB
It is regulated in the following manner
Activated by proinflammatory cytokines and in response to physical and chemical stresses, including osmotic stress, oxidative stress, arsenic and ultraviolet light irradiation. Activated by 'Lys-63'-linked polyubiquitination and by autophosphorylation. Association with TAB1/MAP3K7IP1 and TAB2/MAP3K7IP2 promotes activation through autophosphorylation, whereas PPM1B/PP2CB, PP2A and PPP6C dephosphorylation leads to inactivation.
