Anti-RP10 antibodies enable researchers to detect and measure the RP10 antigen in biological samples. This target is a reported synonym of the IMPDH1 gene, which encodes inosine monophosphate dehydrogenase 1. This protein is known to catalyze the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. The human version of RP10 has a canonical amino acid length of 514 residues and a protein mass of 55.4 kilodaltons, although 7 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include IMPD, IMPD1, and IMPDH-I.
