Isolating Interaction-Null/Impaired Mutants Using the Yeast Two-Hybrid Assay
December 29th, 2023
The interactions of biomolecules, such as protein-protein interactions, are the molecular basis of biological functions. If interaction-null/impaired mutants that specifically lack the relevant interaction can be isolated, they will greatly help to understand the function(s) of this interaction. This article presents an efficient way to isolate interaction-null/impaired mutants.
We are interested in understanding the regulatory mechanisms of the cell cycle in Eukaryotes, especially the relationship between DNA replication, stable germ maintenance, and cell proliferation. The progression of the cell cycle is regulated by cyclin-dependent kinases, or CDKs, in Eukaryotes. This is the case for the initiation of DNA replication.
We have identified a way, on substrates of CDKs, to initiate DNA replication. To understand the function of the protein of your interest, a comparison of the wild-type and mutant is a direct and effective way. Yeast two-hybrid assay, being simple detection and will enhance the process of isolating interaction-null mutants.
This will contribute to advancement of research in the field.
