Anti-refilin B antibodies are used for the immunodetection of the protein encoded by the RFLNB gene. In humans, the canonical protein has a reported length of 214 amino acid residues and a mass of 22.9 kDa. Its subcellular localization is in the cytoplasm. A member of the Refilin protein family, it is reported to be involved in regulation of the perinuclear actin network and nuclear shape through interaction with filamins. Other names for this target antigen include filamin-interacting protein FAM101B, protein FAM101B, regulator of filamin protein B, and family with sequence similarity 101, member B. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species. Western Blot is the most common application for the refilin B antibodies listed below. Immunocytochemistry and Immunofluorescence are also common applications.
