WebExonic circRNA biogenesis is also tightly dependent on trans-factors as RBPs; indeed, binding sites for FUS and QKI occur in the flanking intron regions [26,27,28,29]. The lack of poly-A tails and 5′ caps in circRNAs, due to their covalently closed structure, allows such molecules to escape from several canonical RNA decay pathways inducing ... WebHaving shown that the intronic regions immediately flanking circularized exon (s) were sufficient to produce circRNA, we chose two circRNAs ( circRNA_7172 and circRNA_1975 ), which were characterized by relatively high expression ( Fig. 3D ), to identify the minimal sequence length for circRNA production ( Fig. 4; Supplemental Fig. S5 ).

WebFor each circRNA, two sets of primers were designed: (1) divergent primers to amplify across the backsplice junction, and (2) convergent primers to amplify a linear region within the circRNA. As exons appear in gDNA in a linear fashion, divergent primers should not amplify with this template (Figure S2A; Table S2).
