Chemogenetic Tools in Focus: Proximity, Conformation, and Sterics
Jiaqi Shen, Guanwei Zhou, Wenjing Wang
Abstract
Abstract Chemogenetic tools are genetically encoded systems regulated by user‐defined chemicals. Their ability to temporally modulate protein functions in specific cell populations has facilitated in‐depth understanding of dynamic biological systems. Many chemogenetic domains have been developed for regulating a wide range of biological processes, ranging from cellular events to animal behaviors. These tools share some common mechanisms, including proximity regulation, conformational change and allosteric control, as well as steric hinderance control. Here in this review, we aim to provide an overview of different chemogenetic tool designs that utilize the above three common mechanisms to control cellular events.
