yeast two-hybrid system

The yeast two-hybrid system is a research technique used to study protein interactions. By introducing two different proteins into yeast cells, scientists can see if they bind together. One protein is fused to a "bait" that can activate a reporter gene, while the other is fused to a "trap." If the two proteins interact, the reporter gene is activated, indicating a successful interaction. This method is valuable for understanding how proteins communicate and function in cells, which can have implications in fields like biology, medicine, and drug development.
