基于荧光蛋白(FP)的遗传编码生物传感器允许实时监测空间和时间中的分子动力学,这对于复杂细胞过程的正常运作和调节至关重要。根据要监测的分子事件的类型,需要应用不同的传感策略以用于基于FP的生物传感器的最佳设计。本文综述了基于FP的基因编码生物传感器的各种传感策略,如移位、荧光共振能量转移(FRET)、分裂FP的重组、pH敏感性、成熟速度等,介绍了每种传感策略的一般原理,讨论了需要考虑的关键因素,并给出了这些FP生物传感器的代表性实例。这些将有助于设计最佳的传感策略,以成功开发基于FP的新型遗传编码生物传感器。
Genetically encoded biosensors based on fluorescent proteins (FPs) allow for the real-time monitoring of molecular dynamics in space and time, which are crucial for the proper functioning and regulation of complex cellular processes. Depending on the types of molecular events to be monitored, different sensing strategies need to be applied for the best design of FP-based biosensors. Here, we review genetically encoded biosensors based on FPs with various sensing strategies, for example, translocation, fluorescence resonance energy transfer (FRET), reconstitution of split FP, pH sensitivity, maturation speed, and so on. We introduce general principles of each sensing strategy and discuss critical factors to be considered if available, then provide representative examples of these FP-based biosensors. These will help in designing the best sensing strategy for the successful development of new genetically encoded biosensors based on FPs.
