Background: IMP Dehydrogenase 1/IMPDH1

IMPDH1 (inosine monophosphate dehydrogenase) is a ubiquitous cytosolic and nuclear enzyme that plays a central role in guanine nucleotide metabolism. It catalyzes the NAD-dependent conversion of inosine monophosphate (IMP) to hypoxanthine monophosphate (XMP) which is a precursor for the synthesis of GMP, guanosine, and guanine. These compounds are critical for DNA synthesis and cell proliferation (1, 2). IMPDH1 associates into a homotetramer of approximately 55 kDa subunits, and the tetramers can aggregate into perinuclear structures (3, 4). IMPDH1 binds to the nucleotides AMP, ATP, IMP, and XMP (4) as well as to single stranded DNA and RNA (5). It is inhibited by the immunosuppressant drug mycophenolic acid (MPA) (3, 6) which induces reversible IMPDH1 aggregation (7). It is required for vascular endothelial cell proliferation and the terminal differentiation of adipocytes (8, 9). Mutations of IMPDH1 are associated with autosomal dominant retinitis pigmentosa (4, 10). Human IMPDH1 shares 98% amino acid sequence identity with mouse and rat IMPDH1. Alternative splicing generates additional isoforms with internal deletions or variable substitutions at the N-terminus.
