Jurkat cells were treated with 25 µg/mL anisomycin for 15 min at 37°C. NIH3T3 cells were UV treated for 3min and then cultured for 1h. Total cell lysates (15µg protein) were resolved by 4-20% Tris-glycine gel electrophoresis, transferred to nitrocellulose, and probed with 0.5-2µg/mL anti-p38 MAPK phospho (Thr180/Tyr182) antibody (clone A16016A) antibody (upper) or loading control β-actin (Poly6221, Cat. No. 622101) antibody (lower). The arrow indicate 29kD isoform. Proteins were visualized using a goat anti-mouse-IgG secondary antibody conjugated to HRP (Cat. No. 405306) and chemiluminescence detection.

Description

Mitogen activated protein kinases (MAPK) are a family of highly conserved intracellular kinases that transduce extracellular signals relayed by surface receptors or various types of damage. Three subfamilies exist in mammals, including ERK, JNK, and p38 kinases. Four p38 MAPK family members have been identified: p38a, p38b, p38g, and p38d. p38a is ubiquitously expressed usually at high levels, whereas p38b is expressed at lower levels. The expression patterns of p38g and p38d are more restricted. Most of the functions that are generally ascribed to p38 MAPKs refer to p38a, which is encoded by the MAPK14 gene. The p38 MAP kinase is activated by treatment of cells with proinflammatory cytokines (e.g. TNF and IL-1) or by exposure of cells to environmental stress (e.g. UV radiation and osmotic shock). This activation results in the phosphorylation of residues Thr180 and Tyr182. Over 100 proteins can be directly phosphorylated by p38a and a significant proportion of them are involved in the regulation of gene expression. In addition, the p38a pathway can control at different levels the production of extracellular signaling molecules, such as cytokines, chemokines, and growth factors.

The p38a signaling pathway has dual role in tumorigenesis. During oncogene-induced tumor initiation and in the early response to carcinogens, p38a mainly acts as a tumor suppressor by maintaining cell homeostasis and eventually inducing cell death. However, p38a function is sometimes altered in the tumor cell so that it favors tumor progression. This might be due to changes in gene expression programs that accompany malignant cell transformation or could be driven by different stimuli available in the microenvironment.

Application Notes

29kD isoform of p38α may show up with longer exposure or hybridization with higher concentration of primary antibody in some cell lines.

Antigen Details

Structure
390 amino acids, predicted molecular weight of p38α is 41kD; molecular weight of other isoforms of p38α range from 29kDa to 35kD.
Distribution

Cytoplasm, nucleaus

Function
Serine/threonine kinase which acts as an essential component of the MAP kinase signal transduction pathway. MAPK14 is one of the four p38 MAPKs which play an important role in the cascades of cellular responses evoked by extracellular stimuli such as proinflammatory cytokines or physical stress leading to direct activation of transcription factors.
Interaction
Component of a signaling complex containing at least AKAP13, PKN1, MAPK14, ZAK and MAP2K3. Binds to a kinase interaction motif within the protein tyrosine phosphatase, PTPRR. Interacts with SPAG9 and GADD45A. Interacts with CDC25B, CDC25C, DUSP1, DUSP10, DUSP16, NP60, SUPT20H and TAB1. Interacts with casein kinase II subunits CSNK2A1 and CSNK2B. Interacts with PPM1D. Interacts with CDK5RAP3; recruits PPM1D to MAPK14 and may regulate its dephosphorylation.
