肺表面活性物质是分布于肺泡内衬的一类磷脂蛋白复合物。而由于磷脂具有两亲性,能与肺表面活性物质中的特异性蛋白相互作用而在肺泡中排列形成磷脂单分子层,从而发挥其降低气液界面表面张力的作用。肺表面活性蛋白B(surfactant protein ...肺表面活性物质是分布于肺泡内衬的一类磷脂蛋白复合物。而由于磷脂具有两亲性,能与肺表面活性物质中的特异性蛋白相互作用而在肺泡中排列形成磷脂单分子层,从而发挥其降低气液界面表面张力的作用。肺表面活性蛋白B(surfactant protein B,SP-B)是肺表面活性蛋白最为重要的特异性蛋白,它的异常常常引起肺部各种疾病,因此SP-B在肺功能维持和修复中起着不可替代的作用。SP-B具有类似于阿米巴穿孔肽超蛋白家族成员的结构,属于鞘脂激活蛋白样蛋白超家族蛋白(SAPLIPs)。通过分析脂质-蛋白相互作用和SP-B的构效关系特点,为基于类似物的药物开发提供理论依据。展开更多
