Anti-family with sequence similarity 188 member A antibodies enable researchers to detect and measure the family with sequence similarity 188 member A antigen in biological samples. This target is a reported synonym of the MINDY3 gene, which encodes MINDY lysine 48 deubiquitinase 3. This protein is known to function in the apoptotic pathway, among other biological roles. The human version of family with sequence similarity 188 member A has a canonical amino acid length of 445 residues and a protein mass of 49.7 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells. family with sequence similarity 188 member A is a member of the MINDY deubiquitinase protein family.
