Anti-SMARCB1 antibodies are used in the immunodetection of the protein SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily b, member 1. In humans, the canonical protein has a reported length of 385 amino acid residues and a mass of 44.1 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the SNF5 protein family, SMARCB1 is an important component of the BAF (hSWI/SNF) complex. The SMARCB1 gene has been associated with the disease, Rhabdoid tumor predisposition syndrome. Synonyms for this target antigen include CSS3, INI-1, INI1, MRD15, PPP1R144, RDT, RTPS1, and BAF47. SMARCB1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 110 citations in the literature describe the use of SMARCB1 antibodies in research. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
