Project description:Brain metastatic breast cancer cells were subjected to HITS-CLIP to identify the targets of the RNA binding protein RBM47 MDA231-BrM2a is characterized in PMID: 19421193; Related data published together with these data are found in GSE53779 Non-clonal brain metastatic breast cancer cells stably expressing Flag-tagged, wild-type RBM47 under a doxycline-inducible promoter were treated for three days with doxycycline then UV-irradiated and subjected to Flag HITS-CLIP
Project description:IMR-32 cells were subjected to lentiviral YRNA infection or nELAVL RNAi and/or UV stress followed by RNAseq analysis to monitor RNA level changes RNA from IMR-32 cells was Trizol extracted, Ribominus selected and submitted for high-throughput sequencing.
Project description:Mammalian RNA complexity is regulated through interactions of RNA-binding proteins (RBPs) with their target transcripts. High-throughput sequencing together with UV-crosslinking and immunoprecipitation (HITS-CLIP) is able to globally map RBP-binding footprint regions at a resolution of ~30-60 nucleotides. Here we describe a systematic way to analyze HITS-CLIP data to identify exact crosslink sites, and thereby determine protein-RNA interactions at single-nucleotide resolution. We found that reverse transcriptase used in CLIP frequently skips the crosslinked amino-acid-RNA adduct, resulting in a nucleotide deletion. Genome-wide analysis of these crosslinking-induced mutation sites (CIMS) in HITS-CLIP data for Nova and Argonaute (Ago) proteins in mouse brain tissue revealed deletions in ~8-20% of mRNA tags, which mapped to Nova and Ago binding sites on mRNA or miRNA. CIMS analysis provides a general and more precise means of mapping protein-RNA interactions than currently available methods and insight into the biochemical properties of such interactions in living tissues.
Project description:Mouse cortex samples from E18.5 wild-type were subjected to HITS-CLIP to detect NOVA2 and NOVA1 binding positions on RNA Overall design: Mouse cortex samples were UV-irradiated and subjected to NOVA2 and NOVA1 HITS-CLIP (detailed desription in accompanying paper)

Project description:In order to identify YBX1 binding sites on tRNA fragments, we performed small-RNA HITS-CLIP on endogenous YBX1 We used a previously published method to perform HITS-CLIP on endogenous YBX1 (Chi SW, et al. 2009, Nature 460:479)
Project description:We performed Ago HITS-CLIP to identify targets of viral and human miRNAs in latently KSHV-infected PEL cells Ago HITS-CLIP was performed in two latently infected PEL cell lines, BCBL-1 and BC-3; Argonaute-immunoprecipitation of UV cross-linked Ago-miRNA-mRNA complexes, followed by RNA isolation, library construction, and high-throughput sequencing (Illumina GAxII); we performed 3 biological replicates for each cell line, two technical (sequencing) replicates of BCBL-1 biological replicate 1
