Anti-ARID4A antibodies are used in the immunodetection of the protein AT-rich interaction domain 4A. In humans, the canonical protein has a reported length of 1257 amino acid residues and a mass of 142.8 kDa. Its subcellular localization is in the nucleus. Up to 3 different isoforms have been reported for this protein. ARID4A is reported to be a DNA-binding protein, which modulates activity of several transcription factors including RB1 (retinoblastoma-associated protein) and AR (androgen receptor) (By similarity). Synonyms for this target antigen include RBBP1, RBP-1, RBP1, AT-rich interactive domain-containing protein 4A, ARID domain-containing protein 4A, and RBBP-1. ARID4A gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some ARID4A antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
