A study in mice and Drosophila demonstrated that the circMBNL1 regulates the production of its linear mRNA counterpart in cis through competition with canonical splicing [Patop et al. DOI:10.15252/embj.2018100836]. A separate review confirmed its role as a splicing competitor that adversely affects canonical pre-mRNA splicing [Misir et al. DOI:10.1038/s41418-022-00948-7]. Research in mammalian neural tissue indicates that the circMBNL1 is synaptically-enriched and abundant in the dendritic arbor, suggesting a role in synaptic function [Mehta et al. DOI:10.1016/j.pneurobio.2020.101746].
