General description

Anti-p38 MAPK Antibody detects endogenous levels of total p38 MAPK protein.

p38 mitogen-activated protein kinase (MAPK), also known as, mitogen-activated protein kinase 14 (MAPK14)/ p38α, is encoded by the gene mapped on human chromosome 6p21.31. The encoded protein is a Ser/Thr kinase composed of 90 to 360 residues. p38α MAPK is ubiquitously expressed. It is found in the cytosol, but it can translocate to the nucleus.


The antiserum was produced against synthesized peptide derived from human p38 MAPK.

Immunogen Range: 147-196


Anti-p38 MAPK antibody produced in rabbit has been used in western blot analysis.

Physical form

Rabbit IgG in phosphate buffered saline (without Mg2+ and Ca2+), pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol.

Biochem/physiol Actions

p38 mitogen-activated protein kinase (MAPK)/MAPK14 (mitogen-activated protein kinase 14) participates in resistance of colon cancer cells to camptothecin-related drugs. This protein is required for the growth of embryos. This gene controls proliferation, differentiation, cell death, adhesion, migration, as well as the response to stress and many metabolic pathways. Genetic variation in p38α leads to deletion or overproduction of myelosuppressive cytokines and result in certain bone marrow failure syndromes.
