Article Title: Investigation of Strand-Selective Interaction of SNA-Modified siRNA with AGO2-MID
doi: 10.3390/ijms21155218
Figure Lengend Snippet: Schematic illustration of the proposed mechanism, by which serinol nucleic acid (SNA)-substituted small interfering RNA (siRNA) reduces off-target activity. In pre-RNA-induced silencing complex (pre-RISC), an interaction between the 5’ terminus of one strand and the MID domain results in selection of that strand for the formation of RISC. Off-target effects can occur if the passenger strand is selected. The presence of the SNA moiety at the 5’ terminus of the passenger strand inhibits the interaction with Argonaute 2 (AGO2)-MID, reducing off-target effects.
