Anti-C9orf117 antibodies enable researchers to detect and measure the C9orf117 antigen in biological samples. This target is a reported synonym of the CFAP157 gene, which encodes cilia and flagella associated protein 157. The human version of C9orf117 has a canonical amino acid length of 520 residues and a protein mass of 60.5 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cytoplasm of cells and notably expressed in the nasopharynx, fallopian tube, endometrium, and bronchus. C9orf117 is a member of the CFAP157 protein family.
