NOS1


Also found in: Acronyms.

NOS1

A gene on chromosome 12q14-qter that encodes neuronal nitric oxide synthase (nNOS), a widely expressed enzyme that produces nitric oxide (NO). A messenger molecule with diverse functions throughout the body, nNOS plays a role in a wide range of physiological and pathological processes, including neurotransmission, neurotoxicity, muscle contraction, sexual function, fluid homeostasis and atherosclerosis.

It is interesting to note that a number of common genes occur irrespective of the organ (heart, kidney, lung) effected in the context of adverse events: erythropoetin (EPO), nitric oxide synthase 1 (NOS1), angitotensin converting enzyme (ACE), vascular endothelial growth factor (VEGFA), endothelin receptor (EDNRA) and the adrenergic [alpha]-1D-receptor (ADRA1D).
La produccion del NO es un proceso complejo, su sintesis esta catalizada por al menos tres isoformas de la sintasa del oxido nitrico (NOS); dos de estas isoformas son constitutivas y calcio dependientes, siendo una de ellas originalmente descrita en las celulas endoteliales (eNOS, NOS3) y la otra en el tejido nervioso (nNOS, NOS1), las cuales han sido luego halladas en otros tejidos; la tercera isoforma (iNOS, NOS2) es inducible por citocinas inflamatorias como la interleucina-1[beta] o el factor de necrosis tumoral alfa (TNF-[alfa]) en los macrofagos y otros tipos de celulas (12, 16).
Three forms have been described: neuronal (nNOS, NOS1), endothelial (eNOS, NOS3) and inducible (iNOS, NOS2).

NO is also produced by the neurons where neuronal nitric oxide synthase (nNOS/ NOS1), another constitutive enzyme, is responsible for its production.
