Protein Networks02:26

Protein Networks

4.7K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Genetic Screens

5.9K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Background:

  • High-throughput protein interaction mapping is crucial for understanding cellular functions and disease.
  • Current methods are insufficient for generating complete proteome-scale interaction maps for complex organisms.
  • Significant efficiency gains are needed for large-scale proteome mapping.

Purpose of the Study:

  • To develop a novel, highly efficient method for large-scale binary protein interaction screening.
  • To introduce Barcode Fusion Genetics-Yeast Two-Hybrid (BFG-Y2H) for multiplexed screening of protein pairs.

Main Methods:

  • Developed Barcode Fusion Genetics-Yeast Two-Hybrid (BFG-Y2H) technology.
  • Utilized Cre recombination to fuse DNA barcodes from distinct plasmids, creating chimeric protein-pair barcodes.
  • Quantified fused barcodes using next-generation sequencing for high-throughput analysis.

Main Results:

  • Successfully applied BFG-Y2H to screen protein pair matrices ranging from 25,000 to 2.5 million pairs.
