PhosphoP

HOMOLOGY

interspecies	homolog to rattus Map3k8 (94.00 pc)
	homolog to murine Map3k8 (93.36 pc)

Homologene

FAMILY	serine/threonine protein kinase family
	MAP kinase kinase kinase subfamily

CATEGORY

enzyme , protooncogene

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,cytosolic

basic FUNCTION	playing a role in the cell cycle
	can activate both the MAP kinase and JNK kinase pathways
	activates IKappaB kinases and thus induces the nuclear production of NF-KappaB
	promotes the production of TNF-alpha and IL-2 during T lymphocyte activation
	regulates IL8 production, which is markedly reduced in presence of KSR2
	required for TLR4 activation of the MEK/ERK pathway
	able to activate NF-KappaB1 by stimulating proteasome-mediated proteolysis of NF-KappaB1/p105
	may be an important mediator of intracellular mechanotransduction in mesenchymal stem cells
	regulator of T helper cell lineage decisions and important functional role in the regulation of Th1 responses
	functioning as a promoter of apoptosis in ischemia/reperfusion injury
	inducing cell migration upon COX2 expression and Erk1/Erk2 activity
	can phosphorylate histone H3 and thus induces cellular transformation through up-regulation of c-fos transcriptional activity

CELLULAR PROCESS	cell cycle, checkpoint

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

signal transduction

a component

forming a ternary complex with NFKB1 and TNIP2

INTERACTION

DNA

RNA

small molecule	metal binding, cofactor, nucleotide,
	Mg2+ as a cofactor
	ATP binding

protein	NFKB1/p105
	interacting with TNIP2
	IKBKB directly phosphorylated MAP3K8 on three serines, including the critical MAP3K8 phosphorylation following LPS stimulation of macrophages

cell & other

REGULATION

activated by	IL1 stimulated activation of the MAP3K8 catalytic subunit
		through the phosphorylation of Thr290 and Ser62

induced by

IL12 in a Stat4-dependent manner

Other	up-regulated by BCL11B
	autophosphorylated
	activated specifically during the S and G2/M phases of the cell cycle
