CircRNA interactions: (a) CircRNA binds with RNA-Binding Proteins (RBPs), such as MBNL1 [80]; (b) circRNAs act as miRNA sponges; (c) EIcircRNA interacts with the U1 Small Nuclear Ribonucleoprotein (snRNP) and then binds to RNA Polymerase II (Pol II) [81]; (d) circRNA translation into proteins. The surface of the molecules MBNL1 and Pol II are modelled according to van der Waals surface (this illustration was created with BioRender.com, accessed on 3 November 2021).
