Description
HPA001400 U-2 OS Image U-2 OS cells were treated with Ribavirin to induce the formation of Rods & Rings. Co-localization shows that IMPDH1/IMPDH2 localizes to Rods & Rings as the staining overlaps with a marker for Rods & Rings.

Description

 IMP (inosine 5'-monophosphate) dehydrogenase 1 (HGNC Symbol)

Entrez gene 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 novo synthesis of guanine nucleotides. Defects in this gene are a cause of retinitis pigmentosa type 10 (RP10). Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2008]
