本研究组的主要研究兴趣是生物大分子复合体(如膜蛋白、超分子蛋白复合体)的结构与功能。我们的研究目标是综合多种结构生物学研究手段(以冷冻电镜技术和蛋白质晶体学技术为主)并发展新的结构研究技术方法,在多空间尺度上(从纳观到介观)、多时间尺度上(从静态到动态)、多层次上(体外和体内),来研究生物系统的高分辨率构造。我们以开展前沿科学研究为核心任务,同时注重培养高素质的人才。在未来的五年内,我们研究组的研究重点包括了四个方面:原位结构生物学技术和应用,超快冷冻电镜技术和应用,三维构造生物学技术和应用,膜蛋白的结构研究和定向改造。
1. 原位结构生物学技术和应用
经过30多年发展,尤其是近年的技术突破,冷冻电子显微术特别是单颗粒技术已成为结构生物学的主要手段之一。而蛋白质机器的原位结构解析是结构生物学的下一个突破点,特别是发展高分辨冷冻电子断层三维重构技术。然而,由于制样困难、原始数据完整度及信噪比低、图像解析复杂等,目前绝大部分蛋白质机器原位结构解析的分辨率还停留在20 埃左右。我们的研究兴趣是着重发展原位结构解析的完整技术平台,完善和优化原位结构解析流程中的冷冻离子减薄制样技术、倾转序列数据采集方法、电子断层三维重构新算法以及高通量高精度的蛋白质机器三维定位、对位和聚类分析算法。利用此技术平台,我们将解析一系列重要蛋白质复合体的原位高分辨率结构。
2. 超快冷冻电镜技术和应用
目前限制冷冻电镜分辨率提高的一个重要因素是生物样品的电子辐照损伤,而超快电镜技术为解决这个问题提供了新的机遇。超快电镜和冷冻电镜的成功结合将使我们可以实现蛋白质机器的低辐照损伤高分辨成像,同时能在多个时间尺度上研究蛋白质机器动态结构变化特征。这个领域在国际上尚未开展系统性的研究。我们的研究兴趣是着重发展生物超快冷冻电镜技术,一方面可以探索生物样品的脉冲电子辐照损伤深层次机制,尝试突破由于电子辐照损伤导致的信噪比瓶颈问题;另一方面对超级捕光复合物等重要蛋白质机器进行时间分辨率冷冻电镜成像,分析其时间分辨率的动态过程。
3. 三维构造生物学技术和应用
生物体组织和器官的三维超微结构对于人类认识自然和治疗疾病都有及其重要的意义。体电子显微学的突破性进展和样品制备技术进步,提高了样品的三维可视化细节,使细胞系统的超分辨率成像达到令人满意的程度。随着连续切片自动收集系统的出现和聚焦离子束扫描电镜的发展,连续切片技术日益成熟,自动化程度也大大提高。这些技术的发展拓展了体电子显微学在生物医学领域的应用。我们的研究兴趣是,联合生物成像中心的队伍建立和发展连续切片体电子显微成像技术、图像对位拼接技术和基于人工智能的图像自动识别分割处理等技术,并利用这一技术与相关单位合作,开展组织器官水平上的三维超微结构研究。
4. 膜蛋白的结构研究和定向改造
膜蛋白在人类和其他物种的生命活动中都起着至关重要的作用,如物质运输、能量转换和信号转导等。解析膜蛋白的三维结构对深入理解膜蛋白的生物学功能,并进行基于结构的分子定向改造,具有非常重要的意义。我们的研究兴趣是发展膜蛋白及其复合体的体外构建表达技术,并利用这些技术研究离子通道、G蛋白偶联受体等重要膜蛋白的结构与功能,在此基础上对膜蛋白进行设计改造,赋予它们新的功能,从而开启它们新的应用场景与应用方向。
