Anti-phospho-MAP Kinase1/2 Antibody

产品说明

一般描述

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. 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.

特异性

Specific for phosphorylated (activated) Erk1 and Erk2. Antibody recognition requires phosphorylation of both the threonine and tyrosine residues of Erk1/Erk2 and will not interact with the non-phosphorylated form of the proteins. Does not cross react with activated SAP Kinase 1 or 2.

免疫原

KLH-conjugated phosphopeptide containing the pTEpY motif of Erk1 and Erk2. Clone: 12D4
