Obiettivo del progetto (Objective)
'The interconnections between intermediary metabolism and regulation of gene expression are relatively poorly understood. A few reports have analysed the ability of some metabolic enzymes to 'moonlight' as RNA-binding proteins, being responsive to small metabolites that often represent co-factors of the enzymes. Building on these observations, it was recently proposed that regulatory networks formed between mRNAs, Enzymes and Metabolites (REM networks) might represent a novel regulatory layer interconnecting intermediary metabolism and post-transcriptional regulation of gene expression.
This project aimes to comprehensively address the largely unexplored territory of cross-talk between intermediary metabolism and post-transcriptional gene regulation by identifying mRNA-binding proteins in living yeast cells using unbiased proteomic and transcriptomic methods. By adaptation of a protocol established in the host lab for human cells, I will employ in vivo crosslinking and oligo d(T)-purification followed by mass spectrometry to create a catalogue of mRNA-binding proteins for yeast, thereby identifying enzymes conserved between human and yeast. To find 'target' RNAs that specifically interact with these enzymes, I will use crosslinking and immunoprecipitation (CLIP/CRAC) assays followed by high-throughput RNA sequencing. This will allow me to identify the interacting motifs in both, the RNA and the enzymes by bioinformatic and biochemical methods. Finally, I will explore the importance of the mRNA-protein interactions for gene regulation using functional assays in vivo and in vitro.'
Introduzione (Teaser)
The idea that proteins have one task is out of date. Many metabolic enzymes go moonlighting and have two roles to fulfil.
