The ROQ domain is composed of three subdomains, I, II and III. This entry describes the second domain, ROQ II. 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].
This domain is found in Roquin-1/2 from humans and in other eukaryotic RING-E3 ubiquitin ligases and transferases. These paralogous proteins Roquin-1/2 recruit the deadenylation and decapping machineries to initiate mRNA degradation. They play a cent ...
This domain is found in Roquin-1/2 from humans and in other eukaryotic RING-E3 ubiquitin ligases and transferases. 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].
