Mitogen-activated protein kinase kinase kinase kinase 4 is an enzyme that in humans is encoded by the MAP4K4 gene.[3][4][5][6]

Function

The protein encoded by this gene is a member of the serine/threonine protein kinase family. This kinase has been shown to specifically activate MAPK8/JNK. The activation of MAPK8 by this kinase is found to be inhibited by the dominant-negative mutants of MAP3K7/TAK1, MAP2K4/MKK4, and MAP2K7/MKK7, which suggests that this kinase may function through the MAP3K7-MAP2K4-MAP2K7 kinase cascade, and mediate the TNF-alpha signaling pathway. Alternatively spliced transcript variants encoding different isoforms have been identified.[6] A recent study showed that MAP4K4 is a direct kinase of LATS1/2 and thus regulates the Hippo pathway effectors YAP and TAZ. [7][8]

Interactions

MAP4K4 has been shown to interact with NCK1[5] and CD29.[9]
