ERK1 Antibodies

Target Information

MAPK3 (ERK1) is a serine/threonine kinase that is an important activator of p90, RSK, MSK, ELK1, and Stat3, and is involved in the MAPK pathway. 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. 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.
