Anti-BAF nuclear assembly factor 1 antibodies are used for the immunodetection of the protein encoded by the BANF1 gene. In humans, the canonical protein has a reported length of 89 amino acid residues and a mass of 10.1 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is widely expressed across many tissue types. A member of the BAF protein family, it is known to be involved with chromatin organization and the response to oxidative stress. Post-translational modifications have been described, including phosphorylation. The gene encoding this protein is implicated in Nestor-Guillermo progeria syndrome. Other names for this target antigen include BCRP1, D14S1460, NGPS, barrier-to-autointegration factor, barrier to autointegration factor 1, and BAF. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish and chimpanzee species.
