Anti-mitogen-activated protein kinase 14 antibodies are used for the immunodetection of the protein encoded by the MAPK14 gene. In humans, the canonical protein has a reported length of 360 amino acid residues and a mass of 41.3 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 5 different isoforms for this protein. A member of the CMGC Ser/Thr protein kinase protein family, it is known to be a serine/threonine kinase that acts as an essential component of the MAP kinase signal transduction pathway. Other names for this target antigen include CSBP1, CSBP2, CSPB1, EXIP, Mxi2, PRKM14, PRKM15, and CSBP. Gene orthologs have been identified in the mouse, rat, bovine, chimpanzee and chicken species. Over 10000 citations in the literature describe the use of mitogen-activated protein kinase 14 antibodies in research. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
