MAP kinase kinase kinase (or MAP3K or MEKK) is a serine/threonine-specific protein kinase which acts upon MAP kinase kinase.
In humans there are at least 19 genes:
Perhaps the best characterized MAP3K are the members of the oncogenic RAF family (RAF1, BRAF, ARAF), which are effectors of mitogenic ras signaling and which activate the ERK1/2 (MAPK3/MAPK1) pathway, through activation of MEK1(MAP2K1) and MEK2(MAP2K2).
MEKK1 activates MAPK8/JNK by phosphorylation of its activator SEK1(MAP2K4).[1]
MAP3K3 directly regulates the MAPK8/JNK and extracellular signal-regulated protein kinase (ERK) pathways by activating SEK and MEK1/2 respectively; it does not regulate the p38 pathway.[2]
MAP3K7(TAK1)participate in regulation of transcription by transforming growth factor-beta (TGF-beta).[3]
MAPK pathway. Many of the MAP3K's here are labelled by their alternative names.
