See all p38 primary antibodies
DescriptionMouse monoclonal [M139] to p38 (phospho T180 + Y182)
SpecificityThis antibody detects a 42 kDa protein corresponding to the apparent molecular mass of p38a. This peptide sequence is highly conserved in the p38ß,g, and d MAPKs, and is identical in human and mouse p38a.
Tested applicationsSuitable for: WB, ELISA, ICC/IFmore details
Species reactivityReacts with: Rat, Human
Predicted to work with: Mouse
Synthetic peptide corresponding to Rat p38 (phospho T180 + Y182) conjugated to Keyhole Limpet Haemocyanin (KLH). Clone M139 was generated from a phospho-p38α (Thr-180/Tyr-182) synthetic peptide (coupled to KLH) corresponding to amino acid residues around threonine 180 and tyrosine 182 of rat p38α.
- Pervanadate treated human Jurkat and A431 cells and anisomycin treated human HeLa cells.

FunctionResponds 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.
Tissue specificityBrain, heart, placenta, pancreas and skeletal muscle. Expressed to a lesser extent in lung, liver and kidney.
Sequence similaritiesBelongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.
Contains 1 protein kinase domain.
DomainThe TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.
modificationsDually phosphorylated on Thr-180 and Tyr-182, which activates the enzyme.
Phosphorylated upon DNA damage, probably by ATM or ATR.
Cellular localizationCytoplasm. Nucleus.

Serum starved HepG2 cells were incubated at 37°C for 30 minutes with vehicle control (0 μM) and different concentrations of (±)-naringenin (ab120958). Increased expression of p38 (phospho T180 + Y182) (
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 5% BSA before being incubated with
μg /ml and ab8227 at 1/1000 dilution overnight at 4°C. Antibody binding was detected using an anti-mouse antibody conjugated to HRP (ab97040) at 1/10000 and visualised using ECL development solution.
