IMD2/YHR216W Protein Information Help

Standard Name Imd2p 1
Systematic Name Yhr216wp
Alias Pur5p 2
ORF Classification Verified
Description Inosine monophosphate dehydrogenase; catalyzes the rate-limiting step in GTP biosynthesis, expression is induced by mycophenolic acid resulting in resistance to the drug, expression is repressed by nutrient limitation; IMD2 has a paralog, YAR073W/YAR075W, that arose from a segmental duplication (1, 3, 4, 5, 6)
Name Description IMP Dehydrogenase 1
