The Two-Hybrid System
The bait and prey fusions are co-expressed in yeast where a physical interaction between X and Y leads to the reconstitution of a functional transcription factor that binds to the promoter of a reporter gene (Fig.1). Consequently, transcription of the reporter gene is switched on. A protein-protein interaction is therefore translated into reporter gene activity which can be detected or measured...
متن کاملYeast two-hybrid system
Introduction The two-hybrid system (THS), first introduced by Fields and Song (1989) (Ref. 1), is a powerful technique for identifying new proteins involved in specific biological processes. It allows for the rapid isolation of the gene that codes for a protein that interacts with a specific protein of interest. Here, we present not a review of the current THS technology but, rather, a comprehe...
متن کاملA combined yeast/bacterial two-hybrid system (YBTH): development and evaluation
Two-hybrid screening is a standard methodology to identify and characterize protein-protein interactions that has become an integral component of many proteomic investigations. The twohybrid system was initially developed using yeast as a host organism. However, bacterial two-hybrid systems have also become common laboratory tools and are preferred in some circumstances, although yeast and bact...
متن کاملA two-stage stochastic programming model for the optimal sizing of hybrid PV/diesel/battery in hybrid electric ship system
Ships play the major role in bulk transportation and they need their special energy system. This paper proposes a stochastic programing method for optimal sizing of a hybrid ship power system with energy storage system (ESS), photovoltaic power (PV) and diesel generator. To account for uncertainties, in this study a two-stage stochastic mixed-integer non-linear programing is used to model the o...
متن کاملMammalian two-hybrid system: a complementary approach to the yeast two-hybrid system.
Here we demonstrate the use of a mammalian two-hybrid system to study protein-protein interactions. Like the yeast two-hybrid system, this is a genetic, in vivo assay based on the reconstitution of the function of a transcriptional activator. In this system, one protein of interest is expressed as a fusion to the Gal4 DNA-binding domain and another protein is expressed as a fusion to the activa...
