Anti-FUS1 antibodies enable researchers to detect and measure the FUS1 antigen in biological samples. This target is a reported synonym of the TUSC2 gene, which encodes tumor suppressor 2, mitochondrial calcium regulator. This protein is known to function in the cell cycle and inflammatory response pathways, among other biological roles. The human version of FUS1 has a canonical amino acid length of 110 residues and a protein mass of 12.1 kilodaltons. FUS1 is a member of the TUSC2 protein family.
