Description
Recombinant human MEK4 (33-end) was expressed in E Coli cells using an N-terminal GST tag. The gene accession number is NM_003010.
MEK4 is a member of the mitogen-activated protein kinase family and is involved in the stress-activated protein kinase pathway where it phosphorylates c-Jun NH2-terminal kinase (1). MEK4 is part of a signaling system that is stimulated in the presence of stress to the cell (including chemotherapy), and it controls differentiation and programmed cell death (apoptosis). MEK4 is central component of signal transduction pathways induced by mitogens and stresses. MEK4 genetic inactivation has been observed in a subset of pancreatic carcinomas, implicating deregulation of the stress-activated protein kinase pathway in pancreatic carcinogenesis (2)
