ROQUIN binds to several key immune-relevant messenger RNA (mRNA) targets through its ROQ domain modulating their stability and influencing macrophage function and the peripheral homeostasis of T cells and B cells. More recently, the E3 ubiquitin ligase activity of the ROQUIN RING domain has been shown to be crucial for T-cell-dependent B-cell responses against infection. Defective ROQUIN activity can culminate in a range of diseases, such as systemic autoimmunity, immunodeficiency, and inflammatory bowel disorder. Here, we provide a current overview of the immunomodulatory role of ROQUIN defined by its ribonucleoprotein-like structure, its repertoire of mRNA targets shared by related RNA-binding enzymes, and its involvement in a range of intracellular signalling pathways central to shaping immune responses.C.G.V. is a recipient of an NHMRC ElizabethBlackburn Fellowship, and funding from NHMRC program andproject grants.© 2016 WILEY-VCH Verlag GmbH & Co.
