Antibodies are purified by protein A and peptide affinity chromatography.\n\u003cb\u003eBackground\u003c\/b\u003e\np38 MAP kinase (MAPK), also called RK (1) or CSBP (2), is the mammalian orthologue of the yeast HOG kinase that participates in a signaling cascade controlling cellular responses to cytokines and stress (1-4). Four isoforms of p38 MAPK, p38α, β, γ (also known as Erk6 or SAPK3), and δ (also known as SAPK4) have been identified. Similar to the SAPK\/JNK pathway, p38 MAPK is activated by a variety of cellular stresses, including osmotic shock, inflammatory cytokines, lipopolysaccharide (LPS), UV light, and growth factors (1-5). MKK3, MKK6, and SEK activate p38 MAPK by phosphorylation at Thr180 and Tyr182. Activated p38 MAPK has been shown to phosphorylate and activate MAPKAP kinase 2 (3) and to phosphorylate the transcription factors ATF-2 (5), Max (6), and MEF2 (5-8). SB203580 (4-(4-fluorophenyl)-2-(4-methylsulfinylphenyl)-5-(4-pyridyl)-imidazole) is a selective inhibitor of p38 MAPK. This compound inhibits the activation of MAPKAPK-2 by p38 MAPK and subsequent phosphorylation of HSP27 (9). SB203580 inhibits p38 MAPK catalytic activity by binding to the ATP-binding pocket, but does not inhibit phosphorylation of p38 MAPK by upstream kinases (10). Although there are many similarities between the four p38 isoforms, there are also some important differences that suggest that the various members may regulate specific functions, and the presence of multiple p38s may provide a mechanism for the generation of tissue-specific or stimulus-specific responses to the activation of the p38 signal transduction pathway (9,10).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nERK-6; ERK3; ERK6; Extracellular signal-regulated kinase 6; MAP kinase 12; MAP kinase p38 gamma; MAPK 12; MAPK12; Mitogen-activated protein kinase 12; mitogen-activated protein kinase 3; Mitogen-activated protein kinase p38 gamma; MK12; P38G; P38GAMMA; PRKM12; SAPK-3; SAPK3; Stress-activated protein kinase 3\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Mk\nSENSITIVITY: Endogenous\nMW (kDa): 46\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46797663830185,"sku":"2307T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-2307t","provider":"Iright","version":"1.0","type":"link"}
