EC Tree
IUBMB Comments
This enzyme is a dual-specific protein kinase and requires mitogen-activated protein kinase kinase kinase (MAPKKK) for activation. It is required for activation of EC 2.7.11.24, mitogen-activated protein kinase. Phosphorylation of MEK1 by Raf involves phosphorylation of two serine residues . Mitogen-activated protein kinase (MAPK) signal transduction pathways are among the most widespread mechanisms of cellular regulation. Mammalian MAPK pathways can be recruited by a wide variety of stimuli including hormones (e.g. insulin and growth hormone), mitogens (e.g. epidermal growth factor and platelet-derived growth factor), vasoactive peptides (e.g. angiotensin-II and endothelin), inflammatory cytokines of the tumour necrosis factor (TNF) family and environmental stresses such as osmotic shock, ionizing radiation and ischaemic injury.

This enzyme is a dual-specific protein kinase and requires mitogen-activated protein kinase kinase kinase (MAPKKK) for activation. It is required for activation of EC 2.7.11.24, mitogen-activated protein kinase. Phosphorylation of MEK1 by Raf involves phosphorylation of two serine residues [5]. Mitogen-activated protein kinase (MAPK) signal transduction pathways are among the most widespread mechanisms of cellular regulation. Mammalian MAPK pathways can be recruited by a wide variety of stimuli including hormones (e.g. insulin and growth hormone), mitogens (e.g. epidermal growth factor and platelet-derived growth factor), vasoactive peptides (e.g. angiotensin-II and endothelin), inflammatory cytokines of the tumour necrosis factor (TNF) family and environmental stresses such as osmotic shock, ionizing radiation and ischaemic injury.

LITERATURE
evolution
the enzyme is a member of the MAP kinase family
malfunction
MKK4 is highly mutated and has a pro-oncogenic role in cancers of pancreatic, breast, colon, prostate, skin, and laryngeal squamous cell. Strong association between -1304T>G (rs3826392) polymorphism in the promoter of MKK4 gene and a decreased risk of sporadic colorectal cancer in a southern Chinese population, overview
metabolism
MKK4 belongs to MAPK pathways known to have involvement in the regulation of apoptosis, inflammation, and tumorigenesis
physiological function
additional information
the transient state of apo npMAP2K4 exists between the canonical kinase fold and the aggregation state. The ATP molecule under physiological conditions allows the transient conformation to rapidly assume the canonical kinase fold but the depletion of ATP under conditions of low levels of bioactivity perhaps enhances the transition to the aggregation state
