Our Approach

ProMisMe

Our Approach

The primary objective of ProMisMe is to develop engineered yeast (Saccharomyces cerevisiae) that serve as discovery platform for compounds capable of rescuing MisMP misfolding. These compounds are sourced from vast libraries of drug-like molecules biosynthesized within these microbes, leveraging a technology that allows for the rapid production and screening of a vast diversity of test molecules. These libraries are screened in the microbial cells that produce them, and the molecules that effectively rescue MisMP misfolding are selected through ultrahigh-throughput screening.

Specific Research Objectives

Protein misfolding lies at the heart of many devastating diseases. By targeting the root causes with precision and innovation, ProMisMe aims to transform the treatment landscape for patients suffering from these debilitating conditions and advance the frontiers of biomedical science forward. 

1.

Microbial Biosynthesis

Microbial biosynthesis of drug-like molecules libraries with greatly expanded diversities, enabling the synthesis of tens of millions to billions of different test molecules.

2.

Ultrahigh-Throughput Screening

Ultrahigh-throughput screening for the identification of chemical rescuers of disease-associated MP misfolding.

3.

Biochemical Evaluation

Evaluation of the effect of the selected molecules on MisMP folding and stability through biochemical and biophysical methods.

4.

Pathogenicity Testing

Evaluation of the effect of selected molecules on promoting the cell-surface accumulation of the target MPs in mammalian cell assays.
ProMisMe

PMDs

ProMisMe is dedicated to discovering therapeutic candidates for two severe PMDs: Usher Syndrome III and Charcot-Marie-Tooth disease. Success in this project will not only provide promising therapeutic leads against these major diseases but also establish a broadly applicable framework for drug discovery targeting various conditions caused by membrane protein misfolding.
