There are a number of ELISA Kits available for the measurement of p38 MAP kinase, another term for the human protein, mitogen-activated protein kinase 14. Other synonyms may include: CSAID-binding protein, MAP kinase 14, MAP kinase Mxi2, MAP kinase p38 alpha, cytokine suppressive anti-inflammatory drug binding protein, mitogen-activated protein kinase p38 alpha, and p38 MAP kinase. It is encoded by the MAPK14 gene to yield a protein 360 amino acids in length and 41.3 kDa in size. However, there are up to 5 reported isoforms. The protein, an enzyme, is categorized into the Protein kinase superfamily, CMGC Ser/Thr protein kinase family, MAP kinase subfamily. Versions of p38 MAP kinase are present in other organisms, including: Mouse, Rat, Fly.
