Anti-Aprt Antibody Picoband®

Adenine phosphoribosyltransferase (APRTase) is anenzymeencoded by theAPRTgene, found inhumanson chromosome 16. It belongs to the purine/pyrimidine phosphoribosyltransferase family. A conserved feature of this gene is the distribution of CpG dinucleotides. This enzyme catalyzes the formation of AMP and inorganic pyrophosphate from adenine and 5-phosphoribosyl-1-pyrophosphate (PRPP) . It also produces adenine as a by-product of the polyamine biosynthesis pathway. A homozygous deficiency in this enzyme causes 2,8-dihydroxyadenine urolithiasis. Two transcript variants encoding different isoforms have been found for this gene.

A synthetic peptide corresponding to a sequence at the C-terminus of mouse APRT, which shares 86.4% and 95.5% amino acid (aa) sequence identity with human and rat APRT, respectively.
