Yeast One-Hybrid Screening
Exploring Protein-DNA Interactions: The Yeast One Hybrid Assay Technique
Yeast one hybrid (Y1H) is a classic molecular biology technique used to study the interactions between DNA and proteins within cells. The research direction is to use the promoter of the target gene as bait to screen for upstream proteins that regulate its expression, such as transcription factors.
The promoter DNA of the bait gene is constructed on the pAbAi vector, linearized and integrated into the genome of Y1HGold, forming the bait yeast strain. The library (prey) protein is fused with the activation domain of GAL4 on the AD vector and transferred into the yeast strain. If a certain prey protein interacts with the bait DNA, GAL4 AD will be recruited to the promoter region of the AbA resistance gene, thereby activating the expression of the AbA resistance gene. In this way, yeast cells containing the interacting protein can grow on the selective medium containing AbA antibiotics, while cells without interaction cannot grow.
Technological Superiority
High-throughput screening swiftly identifies proteins interacting with a target.
Reliable results from yeast cell expression systems reflect in vivo conditions.
High sensitivity captures even weak or transient protein interactions.
