Product Description
Specificity / Sensitivity
Phospho-p44/42 MAPK, Phospho-SAPK/JNK and Phospho-p38 MAPK Antibodies only recognize the phosphorylated forms of p44/42 MAPK, SAPK/JNK and p38 MAPK, respectively. They do not significantly cross-react with other MAPK family members.
Source / Purification
Monoclonal antibodies are produced by immunizing animals with synthetic phosphopeptides surrounding Thr180/Tyr182 of human p38 MAPK, Thr202/Tyr204 of human p44 MAPK or Thr183/Tyr185 of human SAPK/JNK.
Background
p44/42 MAPK (Erk1/2), SAPK/JNK, and p38 MAPK function in protein kinase cascades that play a critical role in the regulation of cell growth, differentiation, and control of cellular responses to cytokines and stress. p44/42 MAPK is activated by growth and neurotrophic factors. Activation occurs through phosphorylation of threonine and tyrosine residues (Thr202 and Tyr204 in human Erk1) at the sequence T*EY* by a single upstream MAP kinase kinase (MEK). SAPK/JNK and p38 MAPK are activated by inflammatory cytokines and by a wide variety of cellular stresses. Activation of SAPK/JNK occurs via phosphorylation at Thr183 and Tyr185 by the dual specificity enzyme SEK/MKK4. Both MKK3 and SEK phosphorylate p38 MAPK on tyrosine and threonine at the sequence T*GY* to activate p38 MAP kinase (1-5).
