HITS-CLIP

From Wikipedia, the free encyclopedia

High-throughput sequencing of RNA isolated by crosslinking immunoprecipitation (HITS-CLIP) is a genome-wide means of mapping protein–RNA binding sites in vivo.[1][2] HITS-CLIP was originally used to generate genome-wide protein-RNA interaction maps for the neuron-specific RNA-binding protein and splicing factor NOVA1 and NOVA2;[2] since then a number of other splicing factor maps have been generated, including those for PTB,[3] RbFox2,[4] SFRS1,[5] and hnRNP C.[6]

HITS-CLIP of the RNA-binding protein Argonaute has been performed for the identification of microRNA targets[7] by decoding microRNA-mRNA and protein-RNA interaction maps in mouse brain,[8][9] and subsequently in Caenorhabditis elegans,[10] embryonic stem cells[11] and tissue culture cells.[12] Recently, improved bioinformatics applied to Argonaute HITS-CLIP enables identification of binding sites with single nucleotide resolution.[13]
