Cell-specific RNA CLIP

Our laboratory has discovered that neurons have unique systems for regulating RNA metabolism that are used by neurons. These neuron-specific RNA binding proteins are encoded by multigene families that encode such regulatory factors as Nova, nElavl, Mbnl and RbFox (NeuN). We developed the CLIP method to precisely map RNA -protein interaction sites in living brain or other tissues with single nucleotide resolution. This has led to new understanding of the function of these proteins in vivo. CLIP is a general method, and we have expanded it to the study of the Fragile-X protein FMRP and Argonaute-microRNA-mRNA ternary interactions, allowing identification of translational control and microRNA binding sites on a transcriptome-wide scale. We will discuss more recent explorations of CLIP in functional annotation of the transcriptome, and a new platform method to undertake CLIP studies in single cell types within the brain. The increasing resolution of CLIP allows new insights into cell-specific roles of RNA regulation in specific paradigms of normal and abnormal cellular physiology.
