Supplementary information

IMPDH2 also known as inosine monophosphate dehydrogenase 2 plays an important role in the de novo synthesis of guanine nucleotides. This enzyme with a molecular mass of approximately 56 kDa catalyzes the conversion of inosine monophosphate (IMP) to xanthosine monophosphate (XMP) an important step in the nucleotide biosynthesis. IMPDH2 is expressed in various tissues across the body with high expression in proliferating cells due to increased nucleotide requirements.
Biological function summary

IMPDH2 functions as a homotetramer forming part of a larger complex that regulates nucleotide levels. This regulation is critical for cell growth differentiation and proliferation. IMPDH2 activity drives the synthesis of guanine nucleotides which are essential for DNA and RNA synthesis influencing cellular communication and energy transfer.

Pathways

The target IMPDH2 has a significant role in the purine nucleotide biosynthesis pathway aligning with other enzymes like GMP synthetase. This pathway is critical in maintaining cellular nucleotide pools. IMPDH2’s activity closely interacts with guanosine monophosphate reductase within the same pathway ensuring the balance between different types of nucleotides necessary for various cellular processes.

Aberrations in IMPDH2 activity link to immunological diseases and cancer. Overexpression or upregulation of this enzyme contributes to the rapid proliferation seen in cancerous cells by maintaining high guanine nucleotide levels. Additionally IMPDH2 serves as a target for immunosuppressive drugs used in autoimmune conditions highlighting its relationship with T- and B-cell proliferation. This positions IMPDH2 in therapeutic strategies alongside its pathway partners to modulate disease outcomes.

Target data

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 (PubMed : 7763314, PubMed : 7903306). Could also have a single-stranded nucleic acid-binding activity and could play a role in RNA and/or DNA metabolism (PubMed : 14766016). It may also have a role in the development of malignancy and the growth progression of some tumors.
