MAPK3 Monoclonal Antibody (OTI4D7), TrueMAB™, OriGene

Description

• ERK1 is widely expressed and involved in the regulation of meiosis, mitosis, and post-mitotic functions in differentiated cells
• Many different stimuli, including growth factors, cytokines, virus infection, ligands for heterotrimeric guanine nucleotide-binding protein (G protein)-coupled receptors and transforming agents, activate the ERK1 and ERK2 pathways
• When growth factors bind to the receptor tyrosine kinase, Ras interacts with Raf, the serine/threonine protein kinase and activates it as well
• Once actived, Raf phosphorylates serine residue in 2 further kinases, MEK1/2, which in turn phosphorylates tyrosine/threonine in extracellular-signal regulated kinase (ERK) 1/2
• Upon activation, the ERKs either phosphorylate a number of cytoplasmic targets or migrate to the nucleus, where they phosphorylate and activate a number of transcription factors such as c-Fos and Elk-1
• Functionally, ERK1 is involved with a signaling cascade that regulates various cellular processes such as proliferation, differentiation, and cell cycle progression in response to a variety of extracellular signals
• ERK1 is activated by upstream kinases, resulting in its translocation to the nucleus where it phosphorylates nuclear targets
• Alternatively spliced transcript variants encoding different protein isoforms of ERK1 have been described.
