Target Information

Arginase-1 (Arg1) is a 35 kDa enzyme that converts L-arginine to urea and L-ornithine, the final step in the urea cycle. The resulting polyamines are important for cell proliferation and detoxification of byproducts from protein degradation. By degrading arginine, Arginase 1 reduces nitric oxide production by depriving NO synthase of its substrate.
In both human and mouse, Arginase 1 is expressed in the liver, neutrophils, myeloid-derived suppressor cells (MDSC), and neural stem cells. In humans, expression is found in blood neutrophils but not in CCR3+ granulocytes. In mice, Arginase 1 is a hallmark of alternatively activated macrophages (M2a).
Arginase-1 may be expressed in myeloid cells infiltrating tumors and is typically found in most hepatocellular carcinomas. Defects in Arginase 1 cause argininemia, an autosomal recessive disorder characterized by hyperammonemia.
