Background:

• The yeast two-hybrid (Y2H) system is a powerful molecular biology technique.
• It is widely used for identifying and analyzing interactions between biological molecules.
• Variants of the Y2H system have expanded its applicability.

Purpose of the Study:

• To characterize the protein-protein interaction network in Saccharomyces cerevisiae.
• To detect and examine protein-protein interactions in their native cellular compartments using cytosolic and membrane-associated Y2H methods.
• To investigate protein-ligand interactions and modulate cellular processes via small-molecule hybrid systems.

Main Methods:

• Application of the yeast two-hybrid system and its variants.
• Utilizing nontranscriptional cytosolic and membrane-associated two-hybrid methods.
• Development and application of small-molecule hybrid systems.

Main Results:

• The Y2H system and its variants are effective for identifying protein-protein, protein-DNA, and protein-RNA interactions.
• The Y2H assay is being applied to the entire proteome of Saccharomyces cerevisiae.
• Novel Y2H methods allow for the study of interactions in their natural cellular environments.
• Small-molecule hybrid systems facilitate the study of protein-ligand interactions and the activation of cellular processes.

Conclusions:
