RNA G-quadruplex (IMAGE)
Caption
G-rich sequences in RNA can fold into G-quartets, which are stabilised by potassium ions (K+). When G-quartets are stacked, they can fold into an RNA G-quadruplex (rG4) motif. rG4s have been found to be linked to cancer, neurological disorders and viral pathogenesis.
