Anti-formin like 1 antibodies are used in the immunodetection of the protein encoded by the FMNL1 gene. In humans, the canonical protein has a reported length of 1100 amino acid residues and a mass of 121.9 kDa. Its subcellular localization is in the cell membrane, cytoplasmic vesicles, and cytoplasm. Alternative splicing is reported to yield 3 different isoforms for this protein. It is found to be expressed in heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas. A member of the Formin homology protein family, it is believed to play a role in the control of cell motility and survival of macrophages (By similarity). Post-translational modifications have been described, including myristoylation. Other names for this target antigen include C17orf1B, FHOD4, FMNL, KW-13, formin-like protein 1, CLL-associated antigen KW-13, leukocyte formin, and C17orf1.
