Anti-C17orf1 antibodies enable researchers to detect and measure the C17orf1 antigen in biological samples. This target is a reported synonym of the FMNL1 gene, which encodes formin like 1. This protein is known to function in cell migration and cytoskeleton organization, among other biological roles. The human version of C17orf1 has a canonical amino acid length of 1100 residues and a protein mass of 121.9 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cell membrane, cytoplasmic vesicles, and cytoplasm of cells and notably expressed in the skin, lymph node, lung, bone marrow, and appendix. C17orf1 is a member of the Formin homology protein family.
