Anti-SRA1 antibodies are used in the immunodetection of the protein steroid receptor RNA activator 1. In humans, the canonical protein has a reported length of 224 amino acid residues and a mass of 24.4 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is reported to be highly expressed in the liver and skeletal muscle and to a lesser extent in the brain. A member of the SRA1 protein family, SRA1 is reported to be a Functional RNA, which acts as a transcriptional coactivator that selectively enhances steroid receptor-mediated transactivation ligand-independently through a mechanism involving the modulating N-terminal domain (AF-1) of steroid receptors. Synonyms for this target antigen include SRAP, STRAA1, pp7684, steroid receptor RNA activator 1 (complexes with NCOA1), steroid receptor RNA activator protein, and SRA. SRA1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of SRA1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
