MAPKAPK2 (MK2)

Mitogen-activated protein kinase activated protein kinase 2; MAP kinase activated protein kinase 2; MAPK activated protein kinase 2; MAPKAP kinase 2

MAP kinase-activated protein kinase 2 (MAPKAPK2) is an enzyme that in humans is encoded by the MAPKAPK2 gene. MAPKAP kinase-2 (MK2) is originally identified by its phosphorylation of glycogen synthase at serine-7 and the corresponding serine in a peptide (GS peptide-1) modelled after the N-terminus of glycogen synthase.

MAPKAP kinase-2 is a novel protein kinase activated by mitogen-activated protein kinase. This MAP kinase activated protein kinase, termed MAPKAP kinase-2, is distinguished from S6 kinase-II (MAPKAP kinase-1) by its response to inhibitors, lack of phosphorylation of S6 peptides and amino acid sequence.
