G-quadruplexes offer a conserved structural motif for NONO recruitment to NEAT1 architectural lncRNA.

The long non-coding RNA NEAT1 serves as a scaffold for the assembly of paraspeckles, membraneless nuclear organelles involved in gene regulation. Paraspeckle assembly requires NEAT1 recruitment of the RNA-binding protein NONO, however the NEAT1 elements responsible for recruitment are unknown. Herein we present evidence that previously unrecognized structural features of NEAT1 serve an important role in these interactions.
