Anti-urocanase domain containing 1 antibodies enable researchers to detect and measure the urocanase domain containing 1 antigen in biological samples. This target is a reported synonym of the UROC1 gene, which encodes urocanate hydratase 1. The human version of urocanase domain containing 1 has a canonical amino acid length of 676 residues and a protein mass of 74.8 kilodaltons, although 2 isoforms have been identified. It is reported to be notably expressed in the liver. Other names for this target antigen include urocanate hydratase, imidazolonepropionate hydrolase, and urocanase 1.
