Anti-FHOS2 antibodies enable researchers to detect and measure the FHOS2 antigen in biological samples. This target is a reported synonym of the FHOD3 gene, which encodes formin homology 2 domain containing 3. This protein is known to function in cytoskeleton organization, among other biological roles. The human version of FHOS2 has a canonical amino acid length of 1422 residues and a protein mass of 158.6 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the cytoplasm of cells. FHOS2 is a member of the Formin homology protein family.
