| Specificity / Sensitivity | p38α MAP Kinase (L53F8) Mouse mAb detects endogenous levels of total p38α MAPK. This antibody does not cross-react with either JNK/SAPK or p42/44 MAPK or other isoforms of p38. |
| Source / Purification | Monoclonal antibody is produced by immunizing animals with a recombinant p38 MAPK protein. Western Blotting
Western blot analysis of extracts from HeLa, NIH/3T3 and C6 cells, using p38α MAPK (L53F8) Mouse mAb. Flow Cytometry
Flow cytometric analysis of Jurkat cells, using p38α MAPK (L53F8) Mouse mAb (blue) compared to a nonspecifc negative control antibody (red). IF-IC
Confocal immunofluorescent analysis of HeLa cells, untreated (left) or anisomycin-treated (right), using p38-alpha MAPK (L53F8) Mouse mAb (green). Actin filaments have been labeled with Alexa Fluor® 555 phalloidin (red). |
| 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).
