Protein Name: Inosine-5'-monophosphate dehydrogenase 2

UniprotKB/SwissProt ID: IMDH2_HUMAN (P12268)

Gene Name: IMPDH2

Synonyms: IMPD2

Organism: Homo sapiens (Human).

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 growth. 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.

Protein Subcellular Localization: Cytoplasm. Nucleus.
