    Functioni

    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 By similarity.By similarity

    Catalytic activityi

    2 L-arginine + 3 NADPH + 4 O2 = 2 L-citrulline + 2 nitric oxide + 3 NADP+ + 4 H2O.

    Binds 1 FMN.By similarity
    Tetrahydrobiopterin (BH4). May stabilize the dimeric form of the enzyme By similarity.By similarity

    Enzyme regulationi

    Stimulated by calcium/calmodulin. Inhibited by n-Nos-inhibiting protein (PIN) which may prevent the dimerization of the protein. Inhibited by NOSIP By similarity.By similarity

    Interactioni

    Subunit structurei

    Homodimer. Interacts with DLG4; the interaction possibly being prevented by the association between NOS1 and CAPON. Forms a ternary complex with CAPON and RASD1. Forms a ternary complex with CAPON and SYN1. Interacts with ZDHHC23. Interacts with NOSIP; which may impair its synaptic location By similarity. Interacts with HTR4 By similarity. Interacts with SLC6A4 By similarity. Interacts (via N-terminal domain) with DLG4 (via N-terminal tandem pair of PDZ domains) By similarity.By similarity
