Cruz-Reyes, Jorge Professor
Positions
We combine approaches in molecular genetics, structural biology, biochemistry, proteomics, and bioinformatics to study the amazing RNA biology of trypanosome parasites. One research line is on an RNA editing process by uridine insertion and deletion that creates amino acid coding triplets in most mRNAs. Yet a single error in the U-changes yields a frame-shift. Trypanosomes split from other eukaryotic lineages over a hundred million years ago, yet this editing has analogies with RNAi, CRISPR/Cas9, mRNA splicing and other systems directed by small non-coding RNAs (ncRNAs).
