Seven-transmembrane receptors, which constitute the largest, most ubiquitous and most versatile family of membrane receptors, are also the most common target of therapeutic drugs. Recent findings indicate that the classical models of G-protein coupling and activation of second-messenger-generating enzymes do not fully explain their remarkably diverse biological actions.
七跨膜受体是膜受体中最大、分布最广泛且功能最多样化的家族,也是治疗药物最常见的靶点。最近的研究结果表明,G蛋白偶联和第二信使生成酶激活的经典模型并不能完全解释它们极为多样的生物学作用。
