Anti-RUNX1T1 antibodies are used in the immunodetection of the protein RUNX1 partner transcriptional co-repressor 1. In humans, the canonical protein has a reported length of 604 amino acid residues and a mass of 67.6 kDa. Its subcellular localization is in the nucleus. Up to 6 different isoforms have been reported for this protein. It is notably expressed in the testis, nasopharynx, fallopian tube, and bronchus. A member of the CBFA2T protein family, RUNX1T1 is reported to be a transcriptional corepressor, which facilitates transcriptional repression via its association with DNA-binding transcription factors and recruitment of other corepressors and histone-modifying enzymes. Synonyms for this target antigen include AML1T1, CBFA2T1, CDR, ETO, MTG8, ZMYND2, protein CBFA2T1, and AML1-MTG8. RUNX1T1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of RUNX1T1 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.
