Anti-Bug22 antibodies enable researchers to detect and measure the Bug22 antigen in biological samples. This target is a reported synonym of the CFAP20 gene, which encodes cilia and flagella associated protein 20. This protein is known to function in cilium assembly, among other biological roles. The human version of Bug22 has a canonical amino acid length of 193 residues and a protein mass of 22.8 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells. Bug22 is a member of the CFAP20 protein family.
