The kink-turn motif
A common RNA structural motif that consists of helix–internal loop–helix motif .


Contents

Introduction

Originally identified in the course of analyzing the large ribosomal subunit[1], this RNA structural motif was also identified in other RNAs. Particular instances have been called the GA motif [2] The kink-turn motif includes the A-minor motif. Many kink-turns bind proteins; however, they also mediate RNA tertiary structure interactions.

Structures Containing the Motif

Drag the structure with the mouse to rotate
  • The Large Ribosomal Subunit contains 9 identified kink-turns: ,Kt-58 of 3cc2. MAKE The location of all of them in the subunit. To see them in greater detail following the appropriate links on this page at a structural database for k-turn motifs in RNA by the Lilley group[3].
  • The human spliceosomal and small nucleolar RNA-binding 15.5kD protein bound to the kink-turn of a U4 spliceosomal RNA fragment (1e7k)[4].
  • A. fulgidus small ribonucleoprotein particle box C/D RNA has a kink-turn that is bound by L7Ae (1rlg)[5] has a kink turn.
  • Pyrococcus furiosus small ribonucleoprotein particle H/ACA box RNA (2hvy)[6] has a kink turn that is bound directly by L7ae in a complex of several proteins.
  • Azoarcus group I intron (1u6b, 1zzn, 3bo2, 3bo3, 3bo4, and 3iin)[7][8][9][10] has a 'reverse' kink-turn. Overlay of the Azoarcus group I intron reverse kink-turn with a typical one (Kt-7) clearly illustrates the difference. PUT A SCENE HERE OF ALIGNMENT OF THIS WITH KT-7 with each Kt colored differently
  • S. cervisiae L30e bound to its pre-mRNA (1t0k)[11] has a kink-turn with a protein bound.
  • S-adenosylmethionine riboswitch regulatory mRNA element from Thermoanaerobacter tengcongensis (2gis[12] has a kink-turn.
  • The lysine riboswitch regulatory mRNA element from Thermotoga maritima (3dox) has a kink-turn
  • 1nkw – The Large Ribosomal Subunit From Deinococcus radiodurans[13]
  • The small ribosomal subunit (2wh1) has two kink-turns.
