HRP-2243 Recombinant Human IMPDH2 Protein $200

Recombinant Human IMPDH2 Protein

Product Name: Recombinant Human IMPDH2 Protein
Catalog #:  HRP-2243
Manufacture:  LD Biopharma, Inc.

Human inosine-5’-monophosphate dehydrogenase 2 (IMPDH2) gene encodes the rate-limiting enzyme in the de novo guanine nucleotide biosynthesis. It is thus involved in maintaining cellular guanine deoxy- and ribonucleotide pools needed for DNA and RNA synthesis. IMPDH2 protein catalyzes the NAD-dependent oxidation of inosine-5'-monophosphate into xanthine-5'-monophosphate, which is then converted into guanosine-5'-monophosphate. This gene is up-regulated in some neoplasms, suggesting it may play a role in malignant transformation. Recent data also indicated that IMPDH2 also plays an important role in neuronal inflammation pathway regulation, and selective inhibit its activity may proves a novel strategy for developing antineuroinflammation therapy.

Full-length human IMPDH2 cDNA (513aa, derived from BC012840) was constructed with codon optimization gene synthesis and expressed with a human N-terminalT7-His-TEV cleavage site Tag (31aa) fusion. This protein was expressed in E. coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
