Endothelial NOS (eNOS) also known as nitric oxide synthase 3 (NOS3) or constitutive NOS (cNOS) is an enzyme that in humans is encoded by the NOS3 gene.Endothelial NOS is a nitric oxide synthase that generates NO in blood vessels and is involved with regulating vascular tone by inhibiting smooth muscle contraction and platelet aggregation. A constitutive Ca2+ dependent NOS provides a basal release of NO.
