摘要
RNA can interact with RNA-binding proteins(RBPs),mRNA,or other non-coding RNAs(ncRNAs)to form complex regulatory networks.High-throughput CLIP-seq,degradome-seq,and RNA-RNA interactome sequencing methods represent powerful approaches to identify biologically relevant ncRNA-target and protein-ncRNA interactions.However,assigning ncRNAs to their regulatory target genes or interacting RNA-binding proteins(RBPs)remains technically challenging.Chemical modifications to mRNA also play important roles in regulating gene expression.Investigation of the functional roles of these modifications relies highly on the detection methods used.RNA structure is also critical at nearly every step of the RNA life cycle.In this review,we summarize recent advances and limitations in CLIP technologies and discuss the computational challenges of and bioinformatics tools used for decoding the functions and regulatory networks of ncRNAs.We also summarize methods used to detect RNA modifications and to probe RNA structure.
