Anti-DFNX1 antibodies enable researchers to detect and measure the DFNX1 antigen in biological samples. This target is a reported synonym of the PRPS1 gene, which encodes phosphoribosyl pyrophosphate synthetase 1. This protein is known to function in nervous system development and protein phosphorylation, among other biological roles. The human version of DFNX1 has a canonical amino acid length of 318 residues and a protein mass of 34.8 kilodaltons, although 2 isoforms have been identified. Other names for this target antigen include ARTS, CMTX5, and DFN2.
