IMPDH1
| View/Edit Human | View/Edit Mouse |
Inosine-5'-monophosphate dehydrogenase 1, also known as IMP dehydrogenase 1, is an enzyme that in humans is encoded by the IMPDH1 gene.[4][5]
Function
IMP dehydrogenase 1 acts as a homotetramer to regulate cell growth. IMPDH1 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.[4]
Clinical significance
Defects in the IMPDH1 gene are a cause of retinitis pigmentosa type 10 (RP10).[4][6][7]
