Anti-MAFK antibodies are used in the immunodetection of the protein MAF bZIP transcription factor K. In humans, the canonical protein has a reported length of 156 amino acid residues and a mass of 17.5 kDa. Its subcellular localization is in the nucleus. It is notably expressed in the placenta. A member of the BZIP protein family, MAFK is known to be involved with the regulation of transcription. Synonyms for this target antigen include P18, transcription factor MafK, basic-leucine zipper transcription factor MafK, and NFE2U. MAFK gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of MAFK antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
