Arginase-2, mitochondrial (ARG2)

Extrahepatic arginase functions to modulate L-arginine bioavailability to nitric oxid synthase (NOS). Arginine metabolism is an essential regulator of innate and adaptive immune responses.

Appears to be involved in negative regulation of the survival capacity of activated CD4(+) and CD8(+) T cells (PubMed:27745970). May contribute to the immune evasion of H.
