Methodology to Identify Poly-ADP-Ribose Polymerase 1 (PARP1)-mRNA Targets by PAR-CLiP.

There is a long list of important RNA-binding proteins (RBP) involved in different steps of gene expression through posttranscriptional modifications: pre-mRNA splicing, mRNA stabilization, polyadenylation, mRNA export from nucleus to the cytoplasm, and translation. The critical role of RNA-protein interaction necessitates a continuous identification of proteins involved in this process. Here we describe the identification of Poly-ADP-Ribose Polymerase 1 (PARP1) as an RNA binding protein involved in RNA splicing.
