Abstract
In the vascular wall, endothelial nitric oxide synthase (eNOS) produces NO to regulate peripheral vascular resistance, tissue perfusion, and blood pressure. In resistance arteries, eNOS couples with α-globin and, through chemical reactions, modulates NO diffusion needed for vascular smooth muscle relaxation. While α-globin protein alone is known to be unstable, the mechanisms that enable α-globin protein expression remain elusive. Here, Lechauve et al. report that arterial endothelium expresses α hemoglobin–stabilizing protein, which acts as a critical chaperone protein for α-globin expression and vascular function.
