Abstract
Ribosome profiling, first developed in 2009, is the gold standard for quantifying and qualifying changes to translation genome-wide (Ingolia et al., Science, 2009). Though first designed and optimized in vegetative budding yeast, it has since been modified and specialized for use in diverse cellular states in yeast, as well as in bacteria, plants, human cells, and many other organisms (Ingolia et al. Science, 2009, reviewed in (Ingolia et al., Cold Spring Harb Perspect Biol, 2019; Brar and Weissman, Nat Rev Mol Cell Biol, 2015)). Here we report the current ribosome profiling protocol used in our lab to study genome-wide changes to translation in budding yeast undergoing the developmental process of meiosis (Brar et al., Science, 2012; Cheng et al., Cell, 2018). We describe this protocol in detail, including the following steps: collection and flash freezing samples, cell lysis and extract preparation, sucrose gradient centrifugation and monosome collection, RNA extraction, library preparation, and library quality control. Almost every step presented here should be directly applicable to performing ribosome profiling in other eukaryotic cell types or cell states.
