Anti-formin-like 3 antibodies enable researchers to detect and measure the formin-like 3 antigen in biological samples. This target is a reported synonym of the FMNL3 gene, which encodes formin like 3. This protein is known to function in cytoskeleton organization and angiogenesis, among other biological roles. The human version of formin-like 3 has a canonical amino acid length of 1028 residues and a protein mass of 117.2 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cell membrane and cytoplasm of cells. formin-like 3 is a member of the Formin homology protein family.
