Active Recombinant Mouse MAP2K4(34-end) Protein, N-GST-tagged

• Cat.No.: MAP2K4-145M
• Product Overview: N-terminal GST-tagged, murine MKK4 residues 34–end, expressed in E.coli cells. Purified using glutathione agarose. Activated by incubation with MEKK and then re-purified using Ni2+/NTA agarose.

Specification

• Description: MKK4 is a member of the mitogen-activated protein kinase (MAPK) family. Members of this family act as an integration point for multiple biochemical signals and are involved in a wide variety of cellular processes such as proliferation, differentiation, transcription regulation, and development. They form a three-tiered signaling module composed of MAPKKKs, MAPKKs, and MAPKs. This protein is phosphorylated at serine and threonine residues by MAPKKKs and subsequently phosphorylates downstream MAPK targets at threonine and tyrosine residues. A similar protein in mouse has been reported to play a role in liver organogenesis.
