![]() ![]() Other versions: HITS-CLIP, PAR-CLIP, eCLIP, irCLIP. Comparing Nova CLIP andiCLIP data revealed that cDNA deletions have a preference for TTT motifs, whereas iCLIP cDNA truncations are more likely to identify clusters of YCAY motifs as the primary Nova binding sites. In iCLIP, specific crosslinked RNA-protein complexes are immunoprecipitated. ![]() This approach includes additional steps to digest the proteins after crosslinking and to map the crosslink sites with reverse transcriptase. Deep sequencing of these amplified fragments provides nucleotide resolution of the protein-binding site eCLIP is an improvement over iCLIP that avoids circularizing the cDNA to reduce artifacts. iCLIP maps protein-RNA interactions, in a process similar to HITS-CLIP and PAR-CLIP (Konig et al., 2010). These circularized fragments are linearized and PCR-amplified. Upon RT, cDNA truncates at the binding site and is circularized. Combined with high-throughput sequencing, CLIP platforms, namely. The complexes are treated with proteinase K, as the protein crosslinked at the binding site remains undigested. UV-C crosslinking immunoprecipitation (CLIP) is a powerful technique for interrogating direct proteinRNA interactions 1, 2. The protocol involves UV irradiation of living cells and. In iCLIP, specific crosslinked RNA-protein complexes are immunoprecipitated. iCLIP is a refinement of CLIP that allows single-nucleotide resolution of RBP binding sites. In iCLIP the crosslinking is also carried out with 254 nm cross-linking, but the method aims to capture the reverse transcription products that stop at the site of crosslinking as opposed to read-through products. ICLIP maps protein-RNA interactions, in a process similar to HITS-CLIP and PAR-CLIP. ![]()
