Biology:MAP3K8
Generic protein structure example |
Mitogen-activated protein kinase kinase kinase 8 is an enzyme that in humans is encoded by the MAP3K8 gene.[1][2][3]
Function
The gene was identified by its oncogenic transforming activity in cells. The encoded protein is a member of the serine/threonine-specific protein kinase family. This kinase can activate ERK1, ERK2 and p38 MAP kinases.[4][5] This kinase was shown to activate IkappaB kinases, and thus induce the nuclear production of NF-kappaB. This kinase was also found to promote the production of TNF-alpha and IL-2 during T lymphocyte activation. Studies of a similar gene in rat suggested the direct involvement of this kinase in the proteolysis of NF-kappaB1, p105 (NFKB1). This gene may also start transcription at a downstream in-frame translation start codon, and thus produce an isoform containing a shorter N-terminus. The shorter isoform has been shown to display weaker transforming activity.[3] In mice, the gene is known as TPL2 and is a tumor-suppressor gene whose absence contributes to the development and progression of cancer.[6] However, it functions in other organs as a oncogene, promoting cancer.[7]
Interactions
MAP3K8 has been shown to interact with AKT1,[8] CHUK,[9] NFKB2,[10] NFKB1,[10][11] C22orf25[12] and TNIP2.[13]
