Easel 76: Unraveling The Role of Helicases in Nonfunctional rRNA Decay

Ribosomes are essential, long-lived, and highly abundant molecular machines responsible for protein synthesis. However, when ribosomes in Saccharomyces cerevisiae are functionally compromised, their ribosomal RNA (rRNA) components are rapidly degraded through a quality control pathway termed nonfunctional ribosomal RNA decay (NRD). We hypothesize that one or more helicases, which disrupt RNA secondary structure, may be important for NRD. Using single gene knock-out strains we are measuring how these helicases affect the growth rate of yeast. To date, we have discovered a slow growth phenotype in two helicase gene deletion strains, ?SKI2 and ?SLH1. We are also investigating how well the NRD pathway is functioning in these mutant strains using RT-qPCR, a technique that quantitatively measures RNA expression. We hope this work will provide insight into the role of helicases in RNA degradation mechanisms and contribute to our understanding of NRD.
