Target Information

Arginase-1 (Arg1) is a 35 kDa enzyme that converts L-arginine to urea and L-ornithine, completing the final step in the urea cycle. The resulting polyamines are essential for cell proliferation and detoxification processes. By degrading arginine, Arginase 1 limits substrate availability for NO synthase, thereby reducing 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, it is expressed in blood neutrophils but not in CCR3+ granulocytes. In mice, Arginase 1 expression is a hallmark of alternatively activated macrophages (M2a).
Arginase-1 may also be expressed in tumor-infiltrating myeloid cells and is commonly found in hepatocellular carcinomas. Mutations in Arginase 1 cause argininemia, an autosomal recessive disorder characterized by hyperammonemia.
