Anti-formin like 3 antibodies are used for the immunodetection of the protein encoded by the FMNL3 gene. In humans, the canonical protein has a reported length of 1028 amino acid residues and a mass of 117.2 kDa. Its subcellular localization is in the cell membrane and cytoplasm. Alternative splicing is reported to yield 3 different isoforms for this protein. It is reported to be expressed in endothelial cells. A member of the Formin homology protein family, it is reported to play a role in the regulation of cell morphology and cytoskeletal organization. Other names for this target antigen include WW domain binding protein 3, formin homology 2 domain-containing protein 3, and formin-like protein 3. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some formin like 3 antibodies may have been used in research and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
