Anti-MED17 antibodies are used in the immunodetection of the protein mediator complex subunit 17. In humans, the canonical protein has a reported length of 651 amino acid residues and a mass of 72.9 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. A member of the Mediator complex subunit 17 protein family, MED17 is a known component of the Mediator complex, a coactivator involved in the regulated transcription of nearly all RNA polymerase II-dependent genes. The MED17 gene has been associated with the disease, Microcephaly. Synonyms for this target antigen include CRSP77, DRIP80, SRB4, TRAP80, mediator of RNA polymerase II transcription subunit 17, and CRSP6. MED17 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some MED17 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
