Gene name Nitric oxide synthase 3
Gene symbol NOS3
Synonyms (NCBI Gene)
ECNOSeNOS
Chromosome 7
Chromosome location 7q36.1
Summary Nitric oxide is a reactive free radical which acts as a biologic mediator in several processes, including neurotransmission and antimicrobial and antitumoral activities. Nitric oxide is synthesized from L-arginine by nitric oxide synthases. Variations in
