Anti-MAP3K4 Antibody detects endogenous levels of total MAP3K4 protein.
MAP3K4 (mitogen-activated protein kinase kinase kinase 4) gene encodes a component of protein kinase signal transduction cascade. It is also termed as MTK1 (MAP3 kinase 1). MAP3K4 contains a protein kinase catalytic domain at the C terminus and a regulatory/autoinhibitory domain at the N-terminus. It is located on human chromosome 6q26.
Immunogen
The antiserum was produced against synthesized peptide derived from human MAP3K4.
Immunogen Range: 1281-1330
Biochem/physiol Actions
MAP3K4 (mitogen-activated protein kinase kinase kinase 4) phosphorylates and activates a specific MAPK kinase (MAPKK) in the cascade through phosphorylation of conserved threonine and/or serine residues. GADD45 (growth arrest and DNA-damage-inducible proteins) proteins interact with and free the autoinhibitory domain from the kinase domain, thus activating MAP3K4. It mediates the activation of p38 MAPK pathway and the JNK (c-Jun N-terminal kinase) pathway induced by environmental stresses.

A variety of cellular stresses activate the stress-responsive mitogen-activated protein (MAP) kinases p38 and JNK. In this study, we studied the activation mechanism of a human MAP kinase kinase kinase, MTK1 (also known as MEKK4), which mediates activation of both
A human homolog of the yeast Ssk2 and Ssk22 mitogen-activated protein kinase kinase kinases (MAPKKK) was cloned by functional complementation of the osmosensitivity of the yeast ssk2delta ssk22delta sho1delta triple mutant. This kinase, termed MTK1 (MAP Three Kinase 1), is
