The 1.25 Å resolution H32:R crystal structure of a 20 nt ribonucleotide that binds to the TREX-2 complex with high affinity shows a double-stranded RNA duplex arranged along a crystallographic 31 axis in which the antiparallel chains overlap by 18 nucleotides and are related by a crystallographic twofold axis. The duplex shows C-A, U-U and C-C noncanonical base pairings together with canonical Watson-Crick A-U and G-C pairs and a G-U wobble. ...[more]
