分离和鉴定基因编码的受体和效应器分子的研究,已发现了许多迄今为止尚未认知的、具有一般受体结构的受体亚型,这是当今分子生物学领域里一个较大的进展。与G蛋白偶联的细胞膜受体,组成了一个非常庞大的受体家族,而其中每一个受体被推定有7个跨膜功 Studies on the isolation and characterization of gene-encoded receptor and effector molecules have found many hitherto unknown and generally accepted receptor subtypes, a major advance in molecular biology today . Cell membrane receptors, which are coupled to G proteins, make up a very large family of receptors, and each of these receptors is presumed to have seven transmembrane functions
