miRNA-target chimeras reveal miRNA 3′-end pairing as a major determinant of Argonaute target specificity. Nat Comm 6: 8864. [ PMC free article] [ PubMed] [ Google Scholar] This method is effective when all the selected cells overflow with text; this ensures proper text cropping. However, if a cell has shorter text, the Fill function will repeat the content until the cell is full. Proximity-CLIP 11 and the related technique APEX-seq 45, 46, 47 allow the determination of RNA distribution to specific subcellular locations. Both techniques rely on the biotinylation of RNAs (exploited in APEX-seq) and proteins (exploited in Proximity-CLIP) by the engineered ascorbic acid peroxidase protein APEX2 (ref. 48), a tool widely used to quantify the localized proteome 49 (Supplementary Table 1). To allow subcellular compartment-specific biotinylation of RNA and proteins, APEX2 is typically fused to specific localization elements 50. In the case of Proximity-CLIP, prior to protein biotinylation, nascent transcripts are labelled with either 4SU or 6SG and cross-linked to interacting RBPs with UV light of 312–365 nm (Fig. 2a). The compartment-specific proteome, including cross-linked RNPs, is then isolated on streptavidin beads and cross-linked RNA fragments are isolated and sequenced following mild RNase digestion. The characteristic mutations in the cDNA resulting from the use of photoreactive nucleosides reveal cross-linked sequences. A distinctive feature of Proximity-CLIP is that the sequencing of RBP-protected footprints allows for both the profiling of localized RNAs and the identification of protein-occupied, possibly regulatory, cis-acting elements on RNA. In contrast to APEX-seq, this approach provides a snapshot of regulatory elements on RNA that are occupied in the examined compartments.

Even when "Overflow" is selected, if there is data that is present in the cells to the right of the text that is set to "Overflow" the text will be clipped. If you want your text to actually overflow into the cells to the right of their location, then the cells to the right must be empty. Heinz, S. et al.

Neu For many RBPs there is no in vitro binding information available to provide expected binding motifs. However, binding motifs can be identified de novo from the CLIP data and the extent of their enrichment provides some measure of data quality. For example, a comparison of publicly available data for polypyrimidine tract binding protein 1 (PTBP1) revealed that whereas all CLIP variants show enrichment of similar motifs, the extent of enrichment varies dramatically between variants, indicating major differences in data specificity 115. There are several caveats to de novo motif discovery using CLIP, as factors unrelated to the studied RBP may result in enrichment of specific sequence motifs. Such factors include the nucleotide preferences of UV cross-linking or the sequence biases of the RNases and RNA ligases used to join adapters to the ends of RNA fragments 22, 29, 79, 115. One way to minimize the impact of these biases is by producing parallel data sets for diverse RBPs from the same type of biological material and then deriving motifs unique for each RBP after correcting for the features that are in common for different RBPs 7, 28, 85, 119.Slobodin, B. & Gerst, J.
