General description

Monoclonal Anti-p38 MAP Kinase, Activated (Diphosphorylated p38) (mouse IgG2a isotype) is derived from the P38-TY hybridoma produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice. The p38 mitogen-activated protein kinases (MAPK) comprises the stress-activated protein kinase (SAPK) 2b, SAPK3 and SAPK4 (also termed p38β-δ). All these kinases contain a glycine residue in their TXY(Thr−Xaa−Tyr motif) activation motif.

Specificity

Reacts specifically with the active diphosphorylated form of p38 MAP kinase and its closely related isoforms. Does not recognize the non-phosphorylated and mono­phosphory­lated forms of the p38 MAP kinase molecule, or the non-phosphorylated, monophosphorylated and diphosphorylated forms of JNK and ERK-MAP kinases. The epitope recognized by the antibody contains the phosphorylated threonine and tyrosine residues within the regulatory site of active p38 MAP kinase (Thr180-Gly181-Tyr182).

Immunogen

Synthetic peptide HTDDEMpTGpYVATR corresponding to the phosphorylated form of p38 MAP kinase activation loop, coupled to KLH.

Application

Monoclonal Anti-p38 MAP Kinase, Activated (Diphosphorylated p38) antibody produced in mouse may be used in immunoblotting, enzyme linked immunosorbent assay (ELISA), immunostaining, western blotting, immunohistochemistry and in immunocytochemistry.

Biochem/physiol Actions

The p38 mitogen-activated protein kinases (MAPK) are activated by phosphorylation of both tyrosine (Y) and threonine (T) residues organized in a TXY motif. The residue in between the two phosphorylated residues determines the specificity of activation of the MAPKs, and is glutamic acid for extracellular-signal regulated kinase (ERK) (TEY), proline for c-Jun N-terminal kinases (JNK) and glycine for p38 MAPK. Phosphorylation of both tyrosine and threonine is essential for the full activation of all MAPKs. ERK generally transmits signals leading to cell proliferation, p38 MAPK and JNK are both mostly stress-responsive kinases3 and have been implicated in cell death in several cellular systems. Antibodies reacting specifically with activated p38 MAPK are useful tools in the study of the intracellular location of p38 MAPK enzymes, and in sorting out the signal transduction pathways of the MAPK superfamily.

Inhibiting MAPK14 (p38α) diminishes cardiac damage in myocardial ischemia. During myocardial ischemia, p38α interacts with TAB1, a scaffold protein, which promotes p38α autoactivation; active p38α (pp38α) then transphosphorylates TAB1. Previously, we solved the X-ray structure of the p38α-TAB1 (residues 384-412)
