Scientific Background: GCK (MAP4K2) is a protein-serine/threonine kinase of the STE group and STE20 family. It participates in the regulation of the MAPK signalling pathway. It acts as a MAPK kinase kinase kinase (MAP4K) and is an upstream activator of the stress-activated protein kinase/c-Jun N-terminal kinase (SAP/JNK) signalling pathway and to a lesser extend of the p38 MAPKs signalling pathway. It is required for the efficient activation of JNKs by TRAF6-dependent stimuli, including pathogen-associated molecular patterns (PAMPs) such as polyinosine-polycytidine (poly(IC)), lipopolysaccharides (LPS), lipid A, peptidoglycan (PGN), or bacterial flagellin. IL-1 and engagement of CD40 also stimulate to a lessor degree GCK-mediated JNKs activation. GCK is important for LPS stimulation of c-Jun phosphorylation and induction of IL-8. It enhances MAP3K1 oligomerization, which may relieve N-terminal mediated MAP3K1 autoinhibition and lead to activation following autophosphorylation. It mediates the JNK signalling pathway and the p38 MAPKs signalling pathway through activation of the MAP3Ks MAP3K10/MLK2 and MAP3K11/MLK3. It may play a role in the regulation of vesicle targeting or fusion. regulation of vesicle targeting or fusion. It has been linked to insulinomas, which are tumours of the pancreas arising from beta cells, and which will secrete insulin.
