Monoclonal Anti-MAP Kinase, Activated (Diphosphorylated ERK-1&2) Chemische Eigenschaften,Einsatz,Produktion Methoden
Verwenden
Antibodies that react specifically with the active form of MAP kinase are useful for the study of the specific activation requirements, differential tissue expression, and intracellular localization of the active form of MAP kinase in normal and neoplastic tissue.
Monoclonal Anti-MAP Kinase, Activated (Diphosphorylated ERK-1&2) may be used for the localization of the active, dually-phosphorylated, form of MAP kinase using various immunochemical assays such as immunoblotting of cultured cells and tissue extracts, ELISA, immunocytochemistry, immunoprecipitation, and in immunohistochemistry (formalin and formaldehyde-fixed sections). Reactivity has been observed with human, bovine, rat, mouse,
Drosophila,
Spodoptera frugiperda, and yeast.
Monoclonal Anti-MAP Kinase, activated (Diphosphorylated ERK-1&2) antibody has been used in plasmid and transient transfection and western blotting.
Allgemeine Beschreibung
MAP kinase (MAPK, mitogen-activated protein kinase is also termed as ERK, extracellular regulated protein kinase). Molecular cloning has established that MAP kinase (ERKs) consists of at least four isoforms: ERK-1 (p44mapk), ERK-2 (p42mapk), ERK-3, and ERK-5. MAP kinase isoforms appear to be widely expressed in the central nervous system, thymus, spleen, heart, lung and kidney. It is also expressed at high levels in PC12 cells and in fibroblasts. MAPK1 is located on human chromosome 22q11. MAPK3 is mapped to human chromosome 16p11.
Biochem/physiol Actions
MAP kinase (MAPK, mitogen-activated protein kinase) plays a crucial role in various signal transduction pathways leading signals of growth factor, as well as G protein-coupled receptors to their intracellular targets. MAP kinase was shown to regulate several cellular processes among them proliferation, differentiation, cellular morphology and oncogenesis. Activation of ERK-1 and ERK-2 in mitogen-stimulated cells is directly mediated by MAP kinase kinase (MAPKK or MEK), a dual-specificity protein kinase, which phosphorylates both threonine and tyrosine residues in the regulatory sites of MAP kinase. Following activation, MAP kinase phosphorylates several nuclear targets, including transcription factors as well as membrane and cytoskeletal proteins. Termination of MAP kinase signalling appears to be mediated by MAP kinase phosphatase, MKP-1, a dual specificity Thr/Tyr phosphatase which dephosphorylates and inactivates MAP kinase.
