Circulating insulin binds to insulin receptors on blood vessel endothelium, leading to activation of endothelial nitric oxide synthase (eNOS), NO-mediated vasodilation and increased perfusion of ...
reducing insulin receptor signaling within endothelial cells. High-resolution phosphoproteomic screens pinpointed serine 205 in PTP1B as the principal site phosphorylated by PKA. Mutating this ...
