Another protocol called eCLIP was published in 2016.

Recently, various improvements to the protocol were proposed to alleviate previous limitations. As a consequence, valuable information about the exact crosslink site can be retained from truncated cDNAs, or more precisely from the read start sites they cause. ICLIP-seq uses a cleavable adapter in combination with an additional circularization step, which allows all cDNA fragments to be amplified and sequenced. The fraction of truncated and thus lost fragments is typically over 80%.

However, due to the ligation of an adapter at the 5' end of the RNA fragments, HITS-CLIP and PAR-CLIP methods only capture cDNAs which are entirely read by the reverse transcriptase, i.e. Such diagnostic events can be used to localize the crosslink position. These crosslinks subsequently increase the probability for base transitions, deletions and truncations during the reverse transcription. All methods use UV light, which causes the formation of crosslinks at protein-RNA interaction sites. The most commonly used protocols in this field are HITS-CLIP, photoactivatable-ribonucleoside-enhanced CLIP (PAR-CLIP) and since 2010 individual-nucleotide CLIP (iCLIP). State-of-the-art technologies using crosslinking and immunopre-cipitation combined with high-throughput sequencing (CLIP-seq) allow a genome-wide binding site detection with high resolution.

In order to fully understand regulatory processes mediated by RBPs it is crucial to accurately determine the full landscape of interactions for a protein of interest. RBPs bind on several sites of both coding and non-coding RNAs with directed but somewhat fuzzy binding affinity for both RNA sequence and structure. Interactions between RNAs and RNA binding proteins (RBPs) play essential roles in both transcriptional and post-transcriptional gene regulation.
