RNA regulation provides a finely tuned and highly co-ordinated control of gene expression. Regulation is mediated by hundreds to thousands of multi-functional RNA-binding proteins which often interact with large sets of RNAs. In this brief review, we focus on a recent work that highlights how the proteins use multiple RNA-binding domains to interact selectively with the different RNA targets. Deconvoluting the molecular complexity of the RNA regulatory network is essential to understanding cell differentiation and function, and requires accurate models for protein–RNA recognition and protein target selectivity. We discuss that the structural and molecular understanding of the key determinant of recognition, together with the availability of methods to examine protein–RNA interactions at the transcriptome level, may provide an avenue to establish these models.

Cryo-electron microscopy density map of a Cowpea Mosaic virus (CPMV) empty virus-like particle (eVLP) at 2.7 Å resolution (EMD-3952). The large (L) subunit is displayed in green and the small (S) subunit in blue. Five S subunits interact to form pronounced turrets at the 5-fold axis. Here we show a view down a two-fold axis. The eVLP was produced by transient co-expression in plants of the precursor of the L and S subunits (VP60) and the virus-encoded protease (24K) required for its processing.
