Structural analysis reveals similarity of domain II to the helix-turn-helix (HTH) fold. Mutagenesis and biochemical studies show that that the HTH fold in domain II contributes to binding dsRNA at the 5'arm [1].

These paralogous proteins Roquin-1/2 recruit the deadenylation and decapping machineries to initiate mRNA degradation. They play a central role in repressing autoimmunity. The ROQ domain, highly conserved, is required for RNA binding and shows a mostly helical structure with a small three-stranded beta-sheet. It bears a winged helix-turn-helix motif, which is involved in the binding of constitutive decay elements-containing stem-loop mRNAs [1-5].
