Recombinant human biotinylated ERK1, His-tagged

Cat.No.: MAPK3-28H
Product Overview: Recombinant human biotinylated Extracellular signal-regulated kinase 1 (ERK1), N-terminally fused to HIS6, was expressed in E.coli. Protein is not phosphorylated and activated by MKKs. Suitable as substrate for kinase activity assays and for western blot analyses.
Description: Extracellular signal-regulated kinase (ERK) is a serine/threonine protein kinase that functions as the major effector of the Ras protein, a small GTPase. The so called "ERK cascade" consists of three enzymes, the initial GTPase-regulated kinase Raf, (MAP3K) that phosphorylates and activates an intermediate kinase MEK (MAP2K) that, in turn, phosphorylates a threonine and a tyrosine residue of the activation loop of the effector kinase ERK (MAPK). Both, ERK1 and ERK2 share a high sequence identity (90%) and are co-expressed in most tissues but differ in their relative abundance. The substrate specificities of the ERK1 and ERK2 protein kinases are very similar. The consensus sequence for ERK1 substrates has been identified as -Pro- Leu-Ser/Thr-Pro. Both kinases are involved in proliferation, differentiation, cell cycle processes, and survival. ERK1 / 2 differentially phosphorylates a variety of nuclear (Elk-1, c-Myc), cytosolic (MNK1/2, Raf) and cytoskeletal (MAP2, Tau) targets. Since the ERK pathway is often up-regulated in human tumors and it represents an attractive target for anticancer drugs development.
