RNA chaperones ensure proper folding, stability, and ribonuclease resistance of RNA, and support the regulatory activities mediated by RNA. In bacteria, three main chaperones – Hfq, ProQ, and CsrA – have been shown to regulate numerous complex processes, including bacterial growth, stress response and virulence. In this review, Katsuya-Gaviria et al. describe relevant novel insights into their common features, including RNA binding properties, unstructured domains, and interplay with other proteins important to RNA metabolism.
