Anti-VPS23 antibodies enable researchers to detect and measure the VPS23 antigen in biological samples. This target is a reported synonym of the TSG101 gene, which encodes tumor susceptibility 101. This protein is known to function in the cell cycle, among other biological roles. The human version of VPS23 has a canonical amino acid length of 390 residues and a protein mass of 43.9 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the membrane, nucleus, and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include TSG10 and tumor susceptibility gene 101 protein.
