Title: "RNA Maps of the Brain"

Robert Darnell

Time and venue: 11.00 a.m. at the Lecture Hall (room 0.10 of the Max Planck Institute of Biophysics, Max-von-Laue-Str. 3, 60438 Frankfurt am Main, Campus Riedberg)

Abstract
The brain has unique systems for regulating RNA metabolism, as exemplified by the neuron-specific RNA binding proteins Nova, Elavl, and RbFox3 (NeuN).  We developed the HITS-CLIP method to precisely map relevant protein-RNA interaction sites in living brain with single nucleotide resolution.  Recently, we have expanded HITS-CLIP to the study of the Fragile-X protein FMRP and Argonaute-microRNA-mRNA ternary interactions, enabling identification of translational control and microRNA binding sites on a transcriptome-wide scale in the brain, respectively.  Overlaying these different sets of maps reveals insights into the dynamics of RNA regulation in the brain, as well as aspects of protein-RNA interaction that do not conform to current understanding of their function.  These exceptions, and new experiments to address them at the single cell level, will be discussed.
