摘要:
The present invention provides compositions and methods for monitoring cellular signal transduction events. In particular, signal transduction events may be monitored by the use of biosensors comprising protein-binding domains, which bind signal-transduction proteins, and fluorescent proteins. Provided herein, therefore, methods for detecting activation of signal transduction proteins or screening for agents that modulate the activity of signal transduction proteins. Also provided are cells comprising the biosensors; lentiviral particles comprising biosensor coding sequence; and kits comprising the lentiviral particles.
摘要:
The present invention provides methods for using endogenous transcriptional control systems to regulate the expression of heterologous protein(s). In particular, targeted genome editing is used to integrate a sequence encoding the heterologous protein(s) in-frame with an endogenous coding sequence such that the expression of the heterologous and endogenous sequences is regulated by the endogenous control system.
摘要:
The present disclosure provides a method for endogenously tagging an endogenous protein in a cell, and a cell comprising an endogenously tagged protein. Also described are cells produced using such a method and a kit comprising a cell having tagged endogenous protein.
