牛！华人科学家同日连发6篇Cell！
今天是生命科学领域的又一个“中国日”！在今日出版的最新一期国际顶尖学术刊物《细胞》中，一共有10篇科研论文得到发表，其中5篇论文来自华人科学家的课题组，占到了半壁江山！此外，今天还有1篇来自华人科学家的研究在《细胞》上在线发表。更关键的是，这些科学家的绝大部分任职单位或通讯单位在中国。正如许多人所评论的那样，“中国生命科学正阔步前进！” 1徐华强教授课题组 Identification of Phosphorylation Codes for Arrestin Recruitment by G Protein-Coupled Receptors G蛋白偶联受体（GPCR）通过与arrestin蛋白相互作用，调控了多种信号通路。为了让arrestin蛋白高亲和度结合，受体的磷酸化是必须的。在本项研究中，徐华强教授课题组使用自由电子激光（X-ray free electron laser），解析了视紫红质（rhodopsi......阅读全文
