Anti-MOK antibodies are used in the immunodetection of the protein MOK protein kinase. In humans, the canonical protein has a reported length of 419 amino acid residues and a mass of 48 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 6 different isoforms have been reported for this protein. It is found to be expressed in the heart, brain, lung, kidney, and pancreas, and at very low levels in the placenta, liver and skeletal muscle. A member of the CMGC Ser/Thr protein kinase protein family, MOK is known to be involved with intracellular signal transduction and protein phosphorylation. Synonyms for this target antigen include RAGE-1, RAGE1, STK30, MAPK/MAK/MRK overlapping kinase, renal cell carcinoma antigen, and RAGE. MOK gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of MOK antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
