Mitogen-activated protein kinase kinase kinase 7-interacting protein 3 is an enzyme that in humans is encoded by the MAP3K7IP3 gene.[3][4][5]


The product of this gene functions in the NF-kappaB signal transduction pathway. The encoded protein, and the similar and functionally redundant protein MAP3K7IP2/TAB2, forms a ternary complex with the protein kinase MAP3K7/TAK1 and either TRAF2 or TRAF6 in response to stimulation with the pro-inflammatory cytokines TNF or IL-1. Subsequent MAP3K7/TAK1 kinase activity triggers a signaling cascade leading to activation of the NF-kappaB transcription factor. The human genome contains a related pseudogene. Alternatively spliced transcript variants have been described, but their biological validity has not been determined.[5]


MAP3K7IP3 has been shown to interact with MAP3K7IP2,[3]MAP3K7IP1[4] and MAP3K7.[3][4]
