Anti-CHS antibodies enable researchers to detect and measure the CHS antigen in biological samples. This target is a reported synonym of the LYST gene, which encodes lysosomal trafficking regulator. This protein is known to function in viral immune response, among other biological roles. The human version of CHS has a canonical amino acid length of 3801 residues and a protein mass of 429.1 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cytoplasm of cells.
