特異性
Phosphorylation site-specific antibody selective for the dually phosphorylated form of the c-Jun N-terminal Kinase (JNK)/Stress-Activated Protein Kinase (SAPK) enzymes containing a phosphate on threonine 183 and tyrosine 185 (human JNK 1 + 2). The antibody has been shown to recognize the endogenous, active forms of JNK 1 + 2 in a variety of cell types following treatment by a broad range of extracellular stimuli [e.g. including 293 cells (human embryonic kidney; +/- ultraviolet light) and PC12 cells (rat pheochromocytoma; +/- sorbital)]. The region of JNK1 and JNK2 surrounding T183 + Y185 has a high degree of similarity to the corresponding regions in JNK3 and thus may cross react with this protein if phosphorylated on the corresponding residues. -

免疫原
Synthetic peptide (Human) derived from the region of JNK 1 + 2 that contains threonine 183 and tyrosine 185, based on the human sequence. This region is conserved among many species including human, rat, mouse, chick, nematode (Caenorhabditis elegans), and fly (Drosophila melanogaster).

特記事項（精製）
Purified from rabbit serum by sequential epitope specific chromatography. The antibody has been negatively preadsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated JNK enzymes. The final product is generated by affinity chromatography using a JNK-derived peptide that is phosphorylated at threonine 183 and tyrosine 185, within the activation loop. Note: It is the dually phosphorylated form of these enzymes that has full enzymatic activity. -

機能
Responds to activation by environmental stress and pro-inflammatory cytokines by phosphorylating a number of transcription factors, primarily components of AP-1 such as JUN, JDP2 and ATF2 and thus regulates AP-1 transcriptional activity. In T-cells, JNK1 and JNK2 are required for polarized differentiation of T-helper cells into Th1 cells (By similarity). Phosphorylates heat shock factor protein 4 (HSF4).
JNK1 isoforms display different binding patterns: beta-1 preferentially binds to c-Jun, whereas alpha-1, alpha-2, and beta-2 have a similar low level of binding to both c-Jun or ATF2. However, there is no correlation between binding and phosphorylation, which is achieved at about the same efficiency by all isoforms. -

Western blot - Anti-JNK1+JNK2 (phospho T183 + Y185) antibody (ab4821)MEF1 cells were incubated at 37°C for 48h with vehicle control (0 µM) and 5 µM of glibenclamide (ab120267) in DMSO. Increased expression of of JNK1+JNK2 (phospho T183 + Y185) (ab4821) correlates with an increase in glibenclamide concentration, as described in literature.
Whole cell lysates were prepared with RIPA buffer (containing protease inhibitors and sodium orthovanadate), 10µg of each were loaded on the gel and the WB was run under reducing conditions. After transfer the membrane was blocked for an hour using 3% milk before being incubated with ab4821 at 1/1000 dilution and ab85139 at 1 µg /ml overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP (ab97051) at 1/10000 dilution and visualised using ECL development solution.

Cells were fixed with 4% paraformaldehyde, permeabilized with 0.25% Triton X-100 and blocked with 5% BSA for 1 hour at room temperature. Samples were incubated with primary antibody (2ug/ml in 1% BSA) for 3 hours at room temperature. An Alexa Fluor® 488-conjugated Goat anti-rabbit IgG polyclonal was used as the secondary antibody (1/400). Nuclei stained with DAPI (blue, panel b), F-actin stained with Alexa Fluor® 594 Phalloidin (red, panel b) and merged images (panel d).

Western blot - Anti-JNK1+JNK2 (phospho T183 + Y185) antibody (ab4821)To demonstrate the phosphorylation of JNK 1 & 2 in a cell based assay, 293 cells were treated with ultraviolet irradiation (UV). Proteins from cell extracts were resolved by SDS-PAGE on a 10% Tris-glycine gel and transferred to nitrocellulose. Membranes were incubated with either 1µ g/mL ab4821 or 1µ g/mL anti-JNK1 pan. After washing, membranes were incubated with goat F(ab’)2 anti-rabbit IgG alkaline phosphatase and bands were detected using the Tropix WesternStar detection method.
