Nitric oxide synthase, inducible (NOS2)

Produces nitric oxide (NO) which is a messenger molecule with diverse functions throughout the body (PubMed:7531687, PubMed:7544004). In macrophages, NO mediates tumoricidal and bactericidal actions.

Also has nitrosylase activity and mediates cysteine S-nitrosylation of cytoplasmic target proteins such PTGS2/COX2 (By similarity). Included in this iNOS-S100A8/9 transnitrosylase complex involved in the selective inflammatory stimulus-dependent S-nitrosylation of GAPDH on'Cys-247' implicated in regulation of the GAIT complicated activity and likely multiple objectives such as ANXA5, EZR, MSN and VIM (PubMed:25417112).
