Anti-refilin A antibodies are used for the immunodetection of the protein encoded by the RFLNA gene. In humans, the canonical protein has a reported length of 216 amino acid residues and a mass of 23.6 kDa. Its subcellular localization is in the cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. 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 FAM101A, protein FAM101A, regulator of filamin protein A, and family with sequence similarity 101, member A. Gene orthologs have been identified in the mouse, rat and chicken species. Western Blot, Immunofluorescence, and Immunohistochemistry are common applications for refilin A antibodies.
