Anti-PARG99 antibodies enable researchers to detect and measure the PARG99 antigen in biological samples. This target is a reported synonym of the PARG gene, which encodes poly(ADP-ribose) glycohydrolase. This protein is known to function in carbohydrate metabolism and homeostasis, among other biological roles. The human version of PARG99 has a canonical amino acid length of 976 residues and a protein mass of 111.1 kilodaltons, although 5 isoforms have been identified. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. PARG99 is a member of the Poly(ADP-ribose) glycohydrolase protein family.
