纯度Protein A purified
纯化说明Purified from rabbit serum by sequential epitope-specific chromatography. The antibody has been negatively preadsorbed using i) non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated p38, and ii) a JNK-derived peptide that is phosphorylated at threonine 183 and tyrosine 185. The final product is generated by affinity chromatography using a p38-derived peptide that is phosphorylated at threonine 180 and tyrosine 182.
Our Abpromise guarantee covers the use of ab4822 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

功能Responds to activation by environmental stress, pro-inflammatory cytokines and lipopolysaccharide (LPS) by phosphorylating a number of transcription factors, such as ELK1 and ATF2 and several downstream kinases, such as MAPKAPK2 and MAPKAPK5. Plays a critical role in the production of some cytokines, for example IL-6. May play a role in stabilization of EPO mRNA during hypoxic stress. Isoform Mxi2 activation is stimulated by mitogens and oxidative stress and only poorly phosphorylates ELK1 and ATF2. Isoform Exip may play a role in the early onset of apoptosis.
组织特异性Brain, heart, placenta, pancreas and skeletal muscle. Expressed to a lesser extent in lung, liver and kidney.
序列相似性Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.
Contains 1 protein kinase domain.
结构域The TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.
翻译后修饰Dually phosphorylated on Thr-180 and Tyr-182, which activates the enzyme.
Phosphorylated upon DNA damage, probably by ATM or ATR.

Peptide Competition: Extracts prepared from HEK-293 (human epithelial cell line from embryonic kidney) cells treated with UV irradiation were resolved on a 10% Tris-glycine gel and transferred to nitrocellulose. Membranes were blocked with a 5% BSA-TBST buffer overnight at 4oC, then were incubated with 0.50 µg/mL ab4822 for two hours at room temperature in a 3% BSA-TBST buffer, following its prior incubation with: the peptide immunogen (1), a generic phosphothreonine containing peptide (2), a generic phosphotyrosine-containing peptide (3), the non-phosphorylated peptide corresponding to the phosphopeptide (4), no peptide (5), the phosphorylated peptide derived from the corresponding region of JNK 1 & 2 (6), and, the phosphorylated peptide derived from the corresponding region of ERK 1 & 2 (7). After washing, membranes were incubated with goat F(ab')2 antirabbit IgG alkaline phosphatase and the signal was detected using the Tropix WesternStar method. The data show that only the phosphopeptide
