Mitogen-activated protein kinase kinase kinase 8 is an enzyme that in humans is encoded by the MAP3K8 gene .[ 5] [ 6] [ 7]
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 .[ 8] [ 9] 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.[ 7] TPL2 and is a tumor-suppressor gene whose absence contributes to the development and progression of cancer.[ 10] [ 11]
MAP3K8 has been shown to interact with AKT1 ,[ 12] CHUK ,[ 13] NFKB2 ,[ 14] NFKB1 ,[ 14] [ 15] C22orf25 [ 16] TNIP2 .[ 17]
