Extracellular-signal-regulated kinases (ERKs), also called mitogen-activated protein kinases (MAPKs), are widely expressed signaling proteins that regulate meiosis, mitosis, and postmitotic functions in differentiated cells. Following activation by upstream kinases, ERKs are translocated to the nucleus, where they perform their regulatory functions. Disruption of ERK-mediated pathways is common in many cancers. Two members of this family were originally identified with 85% sequence similarity, called ERK1 and ERK2. ERK1 is also known as MAPK3, extracellular signal-regulated kinase 1, insulin-stimulated MAP2 kinase, microtubule-associated protein 2 kinase, PRKM3, ERT2, p44-ERK1, p44-MAPK, HS44KDAP, HUMKER1A, MAP kinase 1, and MAPK1. ERK2 is also known as MAPK1, extracellular signal-regulated kinase 2, PRKM1, PRKM2, ERT1, p41-ERK1, p41-MAPK, p42-MAPK, MAP kinase 1, MAP kinase 2, MAPK1, MAPK2, p38, p40, and p41.
This product is an affinity-purified IgG antibody that recognizes human ERK1 and ERK2 proteins. The antibody was raised in mouse using a recombinant protein, and can be used for Western blot (WB) detection of human ERK1 and ERK2 proteins.
