Anti-RFLNA antibodies are used in the immunodetection of the protein refilin A. 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. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the testis, stomach, small intestine, and fallopian tube. A member of the Refilin protein family, RFLNA is reported to be involved in regulation of the perinuclear actin network and nuclear shape through interaction with filamins. Synonyms for this target antigen include filamin-interacting protein FAM101A, protein FAM101A, regulator of filamin protein A, and family with sequence similarity 101, member A. RFLNA gene orthologs have been reported in the mouse, rat and chicken species. Western Blot, Immunofluorescence, and Immunohistochemistry are common applications for RFLNA antibodies.
