Activity summary

Arginase 2 (Arg2) also known as AII is an enzyme with a molecular weight of approximately 39 kDa. It is part of the urea cycle and functions to hydrolyze L-arginine into L-ornithine and urea. Arg2 is a mitochondrial enzyme mainly expressed in the liver kidney and prostate. Its expression can extend to other tissues such as the small intestine in some conditions and its activity is important in regulating arginine availability for various physiological processes.

Biological function summary

Arg2 plays a role in nitrogen disposal and polyamine synthesis. As part of an enzymatic complex it contributes to the urea cycle which is important for the removal of excess nitrogen from the body. Arginase activity also influences the balance of nitric oxide synthesis as it competes with nitric oxide synthase for their common substrate L-arginine. This competition affects cellular functions which rely on nitric oxide signaling for developing proper vascular and immune responses.

Pathways

Arg2 is an important player in the urea cycle and the polyamine synthesis pathway. It works alongside the enzymes involved in these processes such as ornithine decarboxylase. Additionally Arg2 has a role in the nitric oxide regulation pathway modulating nitric oxide levels by limiting the availability of L-arginine for nitric oxide synthase. This makes Arg2 essential for metabolic processes and cellular communication.

Associated diseases and disorders

Altered Arg2 expression has been associated with cardiovascular diseases and renal complications. For instance disruptions in Arg2 function can lead to endothelial dysfunction influencing conditions like atherosclerosis. Arg2 imbalances are also linked to kidney diseases possibly due to its critical role in ammonia detoxification and renal arginine metabolism. Its interaction with other proteins such as nitric oxide synthase further emphasizes its relevance in these health conditions.
