Anti-double PHD fingers 2 antibodies are used for the immunodetection of the protein encoded by the DPF2 gene. In humans, the canonical protein has a reported length of 391 amino acid residues and a mass of 44.2 kDa. Its subcellular localization is in the nucleus and cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. It is ubiquitously expressed across many tissue types. A member of the Requiem/DPF protein family, it is known to play an active role in transcriptional regulation by binding modified histones H3 and H4. Other names for this target antigen include REQ, SMARCG2, UBID4, ubi-d4, zinc finger protein ubi-d4, BAF45D, BRG1-associated factor 45D, and CSS7. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of double PHD fingers 2 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.
