| Specificity / Sensitivity | p38α MAPK Antibody detects endogenous levels of total p38α MAPK, regardless of its phosphorylation state. This antibody does not cross-react with other p38 MAPK isoforms such as β, γ or δ. |
| Source / Purification | Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the carboxy-terminal residues of human p38α MAPK. Antibodies are purified by protein A and peptide affinity chromatography. Western Blotting
Western blot analysis of extracts from HeLa, NIH/3T3, PC12 and COS cells, using p38α MAPK Antibody. Western Blotting
Western blot analysis of extracts from Xenopus oocytes overexpressing Myc-tagged p38 isoforms, using p38α MAPK Antibody (upper) and Myc-Tag Antibody (lower) to demonstrate the isoform specificity of p38α MAPK Antibody. (Provided by Dr. Eusebio Perdiguero and Dr. Angel Nebreda, European Molecular Biology Laboratory, Germany.) IHC-P (paraffin)
Immunohistochemical analysis of paraffin-embedded human breast carcinoma, showing cytoplasmic and nuclear localization, using p38α MAPK Antibody. |
| Background | p38 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).
