Scientific Background The extracellular signal-regulated kinases 1 and 2 (ERK1 and ERK2), also called p44 and p42 MAP kinases, are members of the Mitogen Activated Protein Kinase (MAPK) family of proteins found in all eukaryotes. Because the 44 kDa ERK1 and the 42 kDa ERK2 are highly homologous and both function in the same protein kinase cascade, the two proteins are often referred to collectively as ERK1/2 or p44/p42 MAP kinase (1). They are both located in the cytosol and mitochondria (2). While the role of cytosol ERK1/2 is well studied and involved in multiple cellular functions (2), the role of mitochondrial ERK1/2 remains poorly understood. Both ERK 1 and 2 are activated by MEK1 or MEK2, by dual phosphorylation of a threonine and tyrosine residue in the activation loop (TEY motif) (1, 3). Either phosphorylation alone can induce an electrophoretic mobility shift, but both are required for activation of the kinase. This dual phosphorylation is efficiently detected by phosphorylation state-specific antibody directed to the pTEpY motif. Once activated, MAP kinases phosphorylate a broad spectrum of substrates, including cytoskeletal proteins, translation regulators, transcription factors, and the Rsk family of protein kinases (4). ERK1/2 activation is generally thought to confer a survival advantage to cells (5); however there is increasing evidence that suggests that the activation of ERK1/2 also contributes to cell death under certain conditions (5). ERK1/2 also is activated in neuronal and renal epithelial cells upon exposure to oxidative stress and toxicants or deprivation of growth factors, and inhibition of the ERK pathway blocks apoptosis (5).

    :

    Anti-ERK1/2 polyclonal antibody (Catalog No. SPC-120, referenced as P132 in the report) was independently validated for use in western blot on human breast adenocarcinoma (MCF7 cell line) whole cell lysate and mouse embryonic fibroblast (NIH3T3 cell line) whole cell lysate at a dilution of 1:5000, with bands detected at the expected molecular weight of 38-43 kDa.Read the full ERK1 antibody comparison report (PDF) prepared by AntibodyResource.comAntibody Resource is spearheading an initiative designed to compare antibodies from numerous suppliers using identical samples/tissues and an identical protocol. In doing so, they hope to enable scientists to form an unrivalled opinion of which is the most suitable antibody for their research and which is going to require the least amount of optimization, a process which can often take weeks or months. For the purposes of the antibody comparison initiative, the best antibodies from each manufacturer were selected and compared side-by-side using the same experimental conditions to provide a direct comparison. The antibodies were collected centrally, repackaged and given an internal reference ID prior to delivery to independent laboratories to ensure objective testing and to minimize bias.“
