Aptamers meet allostery.
Engineered RNAs have demonstrated remarkable properties of molecular recognition and allosteric function. Liu and colleagues now report the isolation and in vivo function of a ligand-dependent RNA-based transcription factor that opens wide the door for allosterically controllable aptamers.
