Kinase: COT mitogen-activated protein kinase kinase kinase 8

Group: STE      Family: STE-Unique      

Description: mitogen-activated protein kinase kinase kinase 8

Gene Symbol: MAP3K8

Synonyms: COT, EST, ESTF, FLJ10486, TPL2, Tpl-2, c-COT

UniprotKB/SwissProt: M3K8_HUMAN (P41279)

Function: Required for TLR4 activation of the MEK/ERK pathway. Able to activate NF-kappa-B 1 by stimulating proteasome-mediated proteolysis of NF-kappa-B 1/p105. Plays a role in the cell cycle. The longer form has some transforming activity, although it is much weaker than the activated cot oncoprotein.

Subcellular Localization: Cytoplasm.
