Anti-NFYA antibodies are used in the immunodetection of the protein nuclear transcription factor Y subunit alpha. In humans, the canonical protein has a reported length of 347 amino acid residues and a mass of 36.9 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the NFYA/HAP2 subunit protein family, NFYA is a known component of the sequence-specific heterotrimeric transcription factor (NF-Y) which specifically recognizes a 5'-CCAAT-3' box motif found in the promoters of its target genes. Synonyms for this target antigen include CBF-B, HAP2, CAAT-box DNA binding protein subunit A, CCAAT-binding transcription factor subunit B, HAP2 CCAAT-binding protein, and CBF-A. NFYA gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of NFYA antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
