[[kink-turn motif|The kink-turn motif]] is a common RNA structural motif that consists of helix–internal loop–helix motif that introduces a very tight kink into the helical axis. Originally identified in the course of analyzing the [[Large Ribosomal Subunit of Haloarcula|large ribosomal subunit]]<ref name="kleinref">PMID: 11483524</ref>, this RNA structural motif was also identified in other RNAs. Particular instances have been called the GA motif <ref>PMID: 11497434</ref>. | [[kink-turn motif|The kink-turn motif]] is a common RNA structural motif that consists of helix–internal loop–helix motif that introduces a very tight kink into the helical axis, as illustrated in the 3D structure window the left.

Many kink-turns bind proteins; however, that trait is not universal. They can mediate RNA tertiary structure interactions as well. | Many kink-turns bind proteins; however, that trait is not universal. They can mediate RNA tertiary structure interactions as well. | ||
