Anti-CXXC11 antibodies enable researchers to detect and measure the CXXC11 antigen in biological samples. This target is a reported synonym of the FBXL19 gene, which encodes F-box and leucine rich repeat protein 19. This protein is known to function in the regulation of transcription, among other biological roles. The human version of CXXC11 has a canonical amino acid length of 694 residues and a protein mass of 75.7 kilodaltons, although 3 isoforms have been identified.
