Anti-FLNA antibodies are used in the immunodetection of the protein filamin A. In humans, the canonical protein has a reported length of 2647 amino acid residues and a mass of 280.7 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. A member of the Filamin protein family, FLNA is reported to promote orthogonal branching of actin filaments and links actin filaments to membrane glycoproteins. Post-translational modifications have been described, including ubiquitination and phosphorylation. The FLNA gene has been associated with the disease, Periventricular nodular heterotopia. Synonyms for this target antigen include ABPX, CSBS, CVD1, FGS2, FLN, FLN1, FMD, and ABP-280. FLNA gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. Over 130 citations in the literature describe the use of FLNA antibodies in research. ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry are common applications for these antibodies.
