ERK1, ACTIVE, GST TAGGED, HUMAN

Description_x000D_ General description_x000D_ ERK1 is a protein serine/threonine kinase that is a member of the extracellular signal-regulated kinases (ERKs), also known as mitogen-activated protein kinase 3 (MAPK3) which are activated in response to numerous growth factors and cytokines. ERK1 is ubiquitously distributed in tissues with the highest expression in heart, brain and spinal cord. Activated ERK1 translocates into the nucleus where it phosphorylates various transcription factors (e.g., Elk-1, c-Myc, c-Jun, c-Fos, and C/EBP beta). ERK pathway is necessary for experience-dependent plasticity and for long-term potentiation of synaptic transmission in the developing visual cortex. ERK activation affects the axonal growth by phosphorylation of microtubule-associated proteins and neurofilaments._x000D_ Physical form_x000D_ Supplied in 50 mM Tris-HCl, pH 7.5, 150 mM NaCl, 10 mM glutathione, 0.1 mM EDTA, 0.25 mM DTT, 0.1 mM PMSF, 25% glycerol._x000D_ Preparation Note_x000D_ After opening, aliquot into smaller quantities and store at -70 °C.
