UniProtKB - Q63562 (M3K8_RAT)
Protein
Mitogen-activated protein kinase kinase kinase 8
Gene
Map3k8
Organism
Rattus norvegicus (Rat)
Status
Functioni
Required for lipopolysaccharide (LPS)-induced, TLR4-mediated activation of the MAPK/ERK pathway in macrophages, thus being critical for production of the proinflammatory cytokine TNF-alpha (TNF) during immune responses. Involved in the regulation of T-helper cell differentiation and IFNG expression in T-cells. Involved in mediating host resistance to bacterial infection through negative regulation of type I interferon (IFN) production. Transduces CD40 and TNFRSF1A signals that activate ERK in B-cells and macrophages, and thus may play a role in the regulation of immunoglobulin production. May also play a role in the transduction of TNF signals that activate JNK and NF-kappa-B in some cell types. In adipocytes, activates MAPK/ERK pathway in an IKBKB-dependent manner in response to IL1B and TNF, but not insulin, leading to induction of lipolysis. Plays a role in the cell cycle.1 Publication

Interactioni
Subunit structurei
Forms a ternary complex with NFKB1/p105 and TNIP2.
Interacts with NFKB1; the interaction increases the stability of MAP3K8 but inhibits its MEK phosphorylation activity, whereas loss of interaction following LPS stimulation leads to its degradation.
Interacts with CD40 and TRAF6; the interaction is required for ERK activation.
Interacts with KSR2; the interaction inhibits ERK and NF-kappa-B activation.
