Jb. Allen et al., FINDING PROSPECTIVE PARTNERS IN THE LIBRARY - THE 2-HYBRID SYSTEM ANDPHAGE DISPLAY FIND A MATCH, Trends in biochemical sciences, 20(12), 1995, pp. 511-516
The two-hybrid system uses the efficacy of yeast genetic assays to ide
ntify protein-protein interactions. It permits the rapid cloning of ge
nes encoding products that interact with a given protein of interest.
Also being developed are phage display methods that allow direct physi
cal selection of binding proteins. These methods have significantly al
tered strategies for analysing signaling and regulatory pathways.
