Gene name Inosine monophosphate dehydrogenase 1
Gene symbol IMPDH1
Synonyms (NCBI Gene)
IMPDIMPD1IMPDH-ILCA11RP10sWSS2608
Chromosome 7
Chromosome location 7q32.1
Summary The protein encoded by this gene acts as a homotetramer to regulate cell growth. The encoded protein is an enzyme that catalyzes the synthesis of xanthine monophosphate (XMP) from inosine-5`-monophosphate (IMP). This is the rate-limiting step in the de no

Protein name Inosine-5'-monophosphate dehydrogenase 1 (IMP dehydrogenase 1) (IMPD 1) (IMPDH 1) (EC 1.1.1.205) (IMPDH-I)
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
