Mitogen-activated protein kinase kinase kinase 1 is an enzyme that in humans is encoded by the MAP3K1 gene.[1][2]

MAP3K, or MEK kinase, is a serine/threonine kinase that occupies a pivotal role in a network of phosphorylating enzymes integrating cellular responses to a number of mitogenic and metabolic stimuli, including insulin (MIM 176730) and many growth factors.[supplied by OMIM][2]

Mouse genetics has revealed that the kinase is important in: correct embryogenesis, keratinocyte migration, T cell cytokine production and B cell antibody production.

Interactions[edit]

MAP3K1 has been shown to interact with C-Raf,[3] MAPK8,[4] TRAF2,[5] MAP2K1,[3] Grb2,[6] MAPK1,[3] AXIN1[7][8] and UBE2I.[9]
