Subcellular location

Subcellular Location:
Cell membrane, sarcolemma; Peripheral membrane protein. Cell projection, dendritic spine

Function

Function:
Produces nitric oxide (NO) which is a messenger molecule with diverse functions throughout the body. In the brain and peripheral nervous system, NO displays many properties of a neurotransmitter. Probably has nitrosylase activity and mediates cysteine S-nitrosylation of cytoplasmic target proteins such SRR.
Catalytic Activity:
2 L-arginine + 3 NADPH + 4 O(2) = 2 L-citrulline + 2 nitric oxide + 3 NADP(+) + 4 H(2)O.
Cofactor:
COFACTOR: Name=heme; Xref=ChEBI:CHEBI:30413; ; COFACTOR: Name=FAD; Xref=ChEBI:CHEBI:57692; ; Note=Binds 1 FAD.;; COFACTOR: Name=FMN; Xref=ChEBI:CHEBI:58210; ; Note=Binds 1 FMN.;; COFACTOR: Name=5,6,7,8-tetrahydrobiopterin; Xref=ChEBI:CHEBI:15372; ; Note=Tetrahydrobiopterin (BH4). May stabilize the dimeric form of the enzyme.;
Enzyme Regulation:
ENZYME REGULATION: Stimulated by calcium/calmodulin. Inhibited by n-Nos-inhibiting protein (PIN) which may prevent the dimerization of the protein. Inhibited by NOSIP.
