Anti-BAP18 antibodies enable researchers to detect and measure the BAP18 antigen in biological samples. This target is a reported synonym of the C17orf49 gene, which encodes chromosome 17 open reading frame 49. This protein is known to function in chromatin organization, among other biological roles. The human version of BAP18 has a canonical amino acid length of 172 residues and a protein mass of 17.9 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types.
