Summary

Protein Function

IMPDH2 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. It 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. (From Uniprot)

Cys Function & Property

Cys331 is one of the active sites of IMPDH2, acts as the thioimidate intermediate during the catalytic process.
