CC -!- FUNCTION: Produces nitric oxide (NO) which is a messenger molecule with
CC diverse functions throughout the body. In macrophages, NO mediates
CC tumoricidal and bactericidal actions. Also has nitrosylase activity and
CC mediates cysteine S-nitrosylation of cytoplasmic target proteins such
CC PTGS2/COX2. As component of the iNOS-S100A8/9 transnitrosylase complex
CC involved in the selective inflammatory stimulus-dependent S-
CC nitrosylation of GAPDH implicated in regulation of the GAIT complex
CC activity and probably multiple targets including ANXA5, EZR, MSN and
CC VIM. Involved in inflammation, enhances the synthesis of pro-
CC inflammatory mediators such as IL6 and IL8.
CC {ECO:0000250|UniProtKB:P35228, ECO:0000250|UniProtKB:P79290}.

CC -!- COFACTOR:
CC Name=(6R)-L-erythro-5,6,7,8-tetrahydrobiopterin;
CC Xref=ChEBI:CHEBI:59560; Evidence={ECO:0000250};
CC Note=Tetrahydrobiopterin (BH4). May stabilize the dimeric form of the
CC enzyme. {ECO:0000250};
CC -!- ACTIVITY REGULATION: Regulated by calcium/calmodulin. {ECO:0000250}.
CC -!- SUBUNIT: Homodimer. Interacts with SLC9A3R1. Interacts with GAPDH;
CC induced by oxidatively-modified low-densitity lipoprotein (LDL(ox)).
CC Interacts with S100A8 and S100A9 to form the iNOS-S100A8/9
CC transnitrosylase complex. Interacts with SPSB1, SPSB2 and SPSB4.
CC Interacts with ELOC and CUL5 in the presence of SPSB1 or SPSB2 or
CC SPSB4. Forms a complex with ASL, ASS1 and HSP90AA1; the complex
CC regulates cell-autonomous L-arginine synthesis and citrulline recycling
CC while channeling extracellular L-arginine to nitric oxide synthesis
CC pathway. {ECO:0000250|UniProtKB:P29477}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol
CC {ECO:0000250|UniProtKB:P35228}. Note=Localizes as discrete foci
CC scattered throughout the cytosol and in the presence of SPSB1 and
CC SPSB4, exhibits a more diffuse cytosolic localization.
CC {ECO:0000250|UniProtKB:P35228}.
CC -!- PTM: Polyubiquitinated; mediated by SPSB1, SPSB2 and SPSB4, leading to
CC proteasomal degradation. {ECO:0000250|UniProtKB:P35228}.
CC -!- SIMILARITY: Belongs to the NOS family. {ECO:0000305}.
