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).
