Research performed in the yeast Saccharomyces cerevisiae has significantly improved our understanding of important cellular phenomona such as regulation of the cell cycle, aging, and cell death. The many benefits of working with S. cerevisiae include the facts that they are inexpensive to grow in the lab and that many ready-to-use strains are now commercially available. Nevertheless, proper maintenance of this organism is critical for successful experiments. This video will provide an overview...

Saccharomyces cerevisiae is a species of yeast that is an extremely valuable model organism. Importantly, S. cerevisiae is a unicellular eukaryote that undergoes many of the same biological processes as humans. This video provides an introduction to the yeast cell cycle, and explains how S. cerevisiae reproduces both asexually and sexually Yeast reproduce asexually through a process known as budding. In contrast, yeast sometimes participate in sexual reproduction, which is important because...

S. cerevisiae are unicellular eukaryotes that are a commonly-used model organism in biological research. In the course of their work, yeast researchers rely upon the fundamental technique of transformation (the uptake of foreign DNA by the cell) to control gene expression, induce genetic deletions, express recombinant proteins, and label subcellular structures. This video provides an overview of how and why yeast transformation is carried out in the lab. The important features of yeast...

Yeast Two-Hybrid Assay to Determine Protein Self-Association in Yeast Cells

2025
This video demonstrates the yeast two-hybrid assay to detect specific protein self-interactions. In this assay, the protein of interest is tagged to two domains of a transcription factor that encodes the β-galactosidase enzyme. When the two proteins interact, this causes transcription and translation to form the enzyme, which is then detected using a biochemical assay.
FAQs
A key strength of the Yeast Model is the ability to alter genes deliberately and then monitor resulting cellular changes. Gene deletion can help examine the consequences of removing a gene, while controlled expression can test how changing gene activity affects processes such as metabolism, protein folding, cell-cycle control, or stress responses. These comparisons support gene-function analysis.
Yeast is a eukaryote, so its cells share fundamental biological features with the cells of more complex organisms. Conserved pathways studied in yeast can therefore reveal general principles of cell-cycle regulation, metabolism, protein folding, and stress responses. However, researchers must interpret these findings carefully because yeast does not reproduce the full organization or interactions of multicellular organisms.
Rapid growth allows investigators to obtain experimental results from yeast over relatively short study periods, while well-characterized genetics supports planned analysis of gene function. Researchers can also combine these advantages with controlled gene deletion or expression and direct monitoring of cells. Together, these features make it easier to compare genetic changes with cellular outcomes across experiments.
A typical investigation begins by selecting a process, such as metabolism or stress response, and identifying genes or cells to alter or monitor. Researchers then use gene deletion, controlled expression, or cellular observation to examine the resulting changes. Comparing those findings with the unaltered system helps connect gene activity to the biological mechanism under study.
Researchers may choose this system when they want to examine disease-related processes through fundamental cellular mechanisms, including protein folding, metabolism, or cell-cycle control. Yeast offers rapid growth and tractable genetics for testing how specific gene changes influence these processes. Results can reveal conserved principles that guide further investigation, but they require validation in more complex biological systems.
In biotechnology, yeast provides a genetically tractable eukaryotic system for investigating cellular processes and gene function. In drug discovery, researchers can use altered or monitored yeast cells to examine disease-related mechanisms and assess how biological pathways respond during experiments. Its value comes from connecting controlled genetic changes with measurable cellular outcomes, while recognizing that yeast is not a complete model of multicellular biology.
