Abstract:
This summary of the 84th Cold Spring Harbor Laboratory (CSHL) Symposium on Quantitative Biology: RNA Control and Regulation, held in May 2019, highlights key emerging themes in this field, which now impacts nearly every aspect of biology and medicine. Recent discoveries accelerated by technological developments reveal enormous diversity of RNAs and RNA-binding proteins (RBPs) with ever-increasing roles in eukaryotes. Atomic structures and live-cell imaging of transcription, RNA splicing, 3'-end processing, modifications, and degradation machineries provide mechanistic insights, explaining hundreds of diseases caused by their perturbations. This great progress uncovered numerous targets for therapies, some of which have already been successfully exploited, and many opportunities for pharmacological intervention and RNA-guided genome engineering. Myriad unexplained RNAs and RBPs leave the RNA field open for many more exciting discoveries.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
