Deep learning of yeast protein production efficiencies
Organisatsiooni nimiBioinformaatika
KokkuvõteBiosustainability concept, where carbon resources are recycled rather than exploited, represents an important economic driving force in the coming decades. Microbial cell factories that are able to utilize industrial by-products (like CO2) or low-value sugars and efficiently produce a variety of chemicals will play a major role in this process, where yeast is one of the preferred host organisms. To make those processes cost effective, we need to understand the cellular regulation mechanisms, where protein production is one of the key elements. Previously collected data on mRNA and protein abundances indicate >1000-fold differences in protein production rates [1]. Understanding these complex regulatory mechanisms using deep learning algorithms would allow one to create novel more efficient platform strains for sustainable production of chemicals [2].

Aim:
Our aim is to create a deep learning algorithm for the yeast genomic data to understand the regulation of protein production based on the experimental data published in Lahtvee et al1.

Work description:
•\tAnalyzing large-scale transcriptomic and proteomic datasets from literature1.
•\tDeveloping a deep learning platform for phenotype predictions2.
•\tPredicting cause-effect relationships for the protein production in yeast.
•\tModel validation based on the experimental data.
