      Background InformationThe 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. The ERK1/2 signaling cascade has been shown to be a critical regulator of cell differentiation, cell physiology and neuronal function. Aberrant control of ERK1/2 activity has been implicated in a variety of pathological conditions, including cancer and autoimmune diseases, and efficient study methods are in demand. Extracellular signal/mitogen activated protein kinases (erk/MAPK) are a group of proline-directed serine/threonine kinases that are activated by dual phosphorylation of conserved threonine and tyrosine residues within a characteristic T X Y peptide motif. The mitogen-activated kinases erk1 (MAPK1) and erk2 (MAPK2) acquire full enzymatic activity upon phosphorylation of both threonine and tyrosine residues within the sequence motif T E Y.

      Entrez Gene Number
      Entrez Gene SummaryThe protein encoded by this gene is a member of the MAP kinase family. MAP kinases, also known as extracellular signal-regulated kinases (ERKs), act in a signaling cascade that regulates various cellular processes such as proliferation, differentiation, and cell cycle progression in response to a variety of extracellular signals. This kinase 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 have been described. ...

      How can I check the phosphospecificity of my antibody once my protein is already immobilized on a membrane?You can check for the phosphospecificity of your antibody using Lambda Protein Phosphatase. Simply perform SDS-polyacrylamide gel electrophoresis (SDS-PAGE) on a cell lysate and transfer the proteins to your membrane of choice. Wash the blotted nitrocellulose twice with water. Block the blotted nitrocellulose in freshly prepared TBS containing 1% bovine serum albumin (BSA) and 0.1% Triton X-100 for 1 hour at 20-25°C with constant agitation. Incubate the nitrocellulose in TBS containing 1% bovine serum albumin (BSA), 0.1% Triton X-100 and 2 mM MnCl2, and where dephosphorylation of proteins is desirable, 400 U/ml Lambda Protein Phosphatase for two hours at room temperature, or overnight at 4°C. After incubation, wash the nitrocellulose in PBS-0.1% Tween 20 for 3-5 minutes. Rinse the nitrocellulose in 4-5 changes of water. Continue with your western blotting assay.
