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 removal of toxins from protein degradation. By degrading arginine, Arginase 1 deprives nitric oxide synthase of its substrate and down-regulates nitric oxide production. 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 occurs in blood neutrophils but not in CCR3+ granulocytes. In mice, Arginase 1 expression is a hallmark of alternatively activated macrophages (M2a). It 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.
