Anti-IMPDHII

Human type II inosine monophosphate dehydrogenase (IMPDHII) is a key enzyme in the purine nucleotide biosynthetic pathway and constitutes a pivotal biological target for immunosuppressant and antiviral drugs. It is linked to cell growth, differentiation, and malignant transformation. IMPDHII also plays an important role in the negative regulation of TLR2 signaling by modulating PI3K activity. Indeed, IMPDHII increases the phosphatase activity of SHP1, which participates in the inactivation of PI3K. Enhanced expression of IMPDHII promotes the tumor metastasis and the advanced tumor progression in patients with prostate cancer. Protein function: Catalyzes 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. Could also have a single-stranded nucleic acid-binding activity and could play a role in RNA and/or DNA metabolism. It may also have a role in the development of malignancy and the growth progression of some tumors. [The UniProt Consortium]
