Schematic representation of mRNA interactions with RNA editing substrate binding, RNA editing core and polyadenylation complexes, and the ribosome. The RNA editing substrate binding complex (RESC) consists of three modules: guide RNA binding (GRBC), RNA editing mediator (REMC) and polyadenylation mediator (PAMC). These modules have been implicated in gRNA stabilization, recruitment of RNA editing core and polyadenylation complexes, respectively [17]. Pre-edited mRNA is depicted in red, edited mRNA is shown in blue, and edited A/U-tailed mRNA is colored in orange. The A/U-tail enables mRNA binding to the small ribosomal subunit (SSU) while RNA editing substrates and complexes are predominantly associated with the large ribosomal subunit (LSU).
