Applications
ApplicationThis Anti-phospho-p38α (Thr180/Tyr182) Antibody is validated for use in IP, WB for the detection of phospho-p38α (Thr180/Tyr182).
Key Applications
  • Immunoprecipitation
  • Western Blotting
Application NotesImmunoblot Analysis: A 1:1,000 dilution of the lot detected p38α dually phosphorylated on residues Thr180 and Tyr182 in lysate from HeLa cells stimulated with anisomycin.

Immunfluorescence: A 1:100 dilution of this antibody detected p38α phosphorylated on both residues, Thr180 and Tyr182, in fixed HeLa cells stimulated with anisomycin.

Immunoprecipitation (IP): 2-5 μL (5-10 μL/mL) of this antibody immunoprecipitated both active p38α from anisomycin treated HeLa whole cell extract and human recombinant GST-p38α, separately, in RIPA buffer.

Immunoprecipitation Kinase Reaction (IPK): 2-5 μL of this lot immunoprecipitated phosphorylated p38α from both anisomycin treated HeLa cells as well as recombinant p38α, separately, and then placed into an in vitro Kinase reaction with recombinant GST-ATF-2 where it phosphorylated ATF-2 on Thr69/71.

Entrez Gene Number
Entrez Gene SummaryThe protein encoded by this gene is a member of the MAP kinase family. MAP kinases act as an integration point for multiple biochemical signals, and are involved in a wide variety of cellular processes such as proliferation, differentiation, transcription regulation and development. This kinase is activated by various environmental stresses and proinflammatory cytokines. The activation requires its phosphorylation by MAP kinase kinases (MKKs), or its autophosphorylation triggered by the interaction of MAP3K7IP1/TAB1 protein with this kinase. The substrates of this kinase include transcription regulator ATF2, MEF2C, and MAX, cell cycle regulator CDC25B, and tumor suppressor p53, which suggest the roles of this kinase in stress related transcription and cell cycle regulation, as well as in genotoxic stress response. Four alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported.

UniProt Number
UniProt SummaryFUNCTION: SwissProt: Q16539 # 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.
COFACTOR: Magnesium.
SIZE: 360 amino acids; 41293 Da
SUBUNIT: Binds to a kinase interaction motif within the protein tyrosine phosphatase, PTPRR. This interaction retains MAPK14 in the cytoplasm and prevents nuclear accumulation. Interacts with SPAG9 (By similarity). Interacts with NP60.
SUBCELLULAR LOCATION: Cytoplasm (By similarity). Nucleus (By similarity).
TISSUE SPECIFICITY: Brain, heart, placenta, pancreas and skeletal muscle. Expressed to a lesser extent in lung, liver and kidney.DOMAIN:SwissProt: Q16539 The TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.
PTM: Dually phosphorylated on Thr-180 and Tyr-182, which activates the enzyme. & Phosphorylated upon DNA damage, probably by ATM or ATR.
SIMILARITY: Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily. & Contains 1 protein kinase domain.
