The post-transcriptional regulatory layer accounts for all the events taking place between transcription and translation and involves a myriad of trans and cis factors densely interconnected. Among the regulatory trans-elements forming this network, RNA-binding proteins (RBPs) play key roles in post-transcriptional regulation of gene expression (PTR). Understanding RBPs behavior is therefore crucial given their participation in all stages of the mRNA life cycle.
