Anti-DPF3 antibodies are used in the immunodetection of the protein double PHD fingers 3. In humans, the canonical protein has a reported length of 378 amino acid residues and a mass of 43.1 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 5 different isoforms for this protein. A member of the Requiem/DPF protein family, it is known to be involved with chromatin remodeling and muscle organ development. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include CERD4, SMARCG3, zinc finger protein DPF3, BRG1-associated factor 45C, D4, zinc and double PHD fingers, family 3, and BAF45C.
