Anti-Formin 2 antibodies are used in the immunodetection of the protein encoded by the FMN2 gene. In humans, the canonical protein has a reported length of 1722 amino acid residues and a mass of 180.1 kDa. Its subcellular localization is in the cytoplasm. Alternative splicing is reported to yield 2 different isoforms for this protein. It is noted to be expressed almost exclusively in the developing and mature central nervous system. A member of the Formin homology protein family, it is reported to be an actin-binding protein that is involved in actin cytoskeleton assembly and reorganization.
