5′ and 3′ UTRs in mRNAs can recruit RNA-binding proteins (RBPs) that enable strong translation as well as aspects of post-transcriptional regulation6. One such family of RBPs is poly(A)-binding proteins (PABPs), which interact with polyadenosine tracts of 12 nt or longer in the 3′ UTR and … See more Synthesis of circRNAs via intron-assisted splicing and RNaseR digestion has been previously described4, but rapid creation of different circRNA species was difficult. To enable higher-throughput testing of circRNAs, we … See more We first sought to uncover principles behind circRNA vector topology that are necessary for strong translation. We began by synthesizing circRNAs with a coxsackievirus B3 (CVB3) IRES (denoted iCVB3) downstream, … See more We previously showed that circRNAs can trigger immune responses in vivo that can be avoided by modifying circRNAs with m6A4,11. However, the effect of m6A incorporation on circRNA translation is unknown. To … See more Viral IRESs are diverse and highly structured RNA regions found primarily in viral 5′ UTRs that promote cap-independent … See more WebNov 18, 2024 · CircRNA is a single-stranded ncRNA which, due to a closed-loop structure secondary to a phosphodiester bond between the 3′ and 5′ ends, as well as the absence of a 3′ polyadenyl tail, has increased stability and a longer half-life compared to linear RNA [ 9 ]. The same structural uniqueness also makes them resistant to nucleases [ 10 ].
