Application

Inosine-5′-monophosphate (5′-IMP) may be used as a substrate to study the activity, specificity and kinetics of inosine 5′-monophosphate dehydrogenase (IMPDH) EC 1.1.1.205, the rate limiting enzyme for the formation of GMP and the guanine nucleotide pool.

Biochem/physiol Actions

Inosine monophosphate, or inosinic acid, is the ribonucleotide of hypoxanthine and the first nucleotide formed during purine synthesis.

Inosine 5'-monophosphate dehydrogenase (IMPDH) catalyzes the first committed step of guanosine 5'-monophosphate (GMP) biosynthesis, and thus regulates the guanine nucleotide pool, which in turn governs proliferation. Human IMPDHs are validated targets for immunosuppressive, antiviral and anticancer drugs, but as yet

The Parkinson's disease (PD)-associated gene leucine-rich repeat kinase 2 (LRRK2) has been studied extensively in the brain. However, several studies have established that mutations in LRRK2 confer susceptibility to mycobacterial infection, suggesting LRRK2 also controls immunity. We demonstrate that loss
