Cell:人类细胞如何对外部环境信号产生反应并加工处理
近日,一项发表于Cell的研究报告中,来自海德堡大学等机构的科学家们利用新型生物技术方法分析了人类细胞如何对外部信号产生反应并加工处理。研究者重点对G蛋白及其受体GPCRs之间的相互作用进行研究,G蛋白是信号传输的介导子,而GPCRs则会诱发信号过程。图片来源:Thomas Splettstoesser (www.sci-style.com) 研究者表示,他们不仅能够更好地理解GPCRs-G蛋白之间的相互作用,还能够有效预测这两者的功能。所有的有机体均能对来自环境中的外部信号产生反应,在人类和其它动物中,这些信号能被细胞膜中的受体(与G蛋白进行偶联)检测到并加工处理,GPCRs是最大的跨膜受体家族,其能对大量细胞外的物理化学信号产生反应,并诱发细胞中的特殊过程,其中一种方法就是与一种或多种G蛋白进行偶联,这项研究中,研究人员就对这些偶联过程进行了深入研究分析。 人类机体中拥有16种G蛋白,其能与近乎1000种GPCRs相......阅读全文
