Abstract: MicroRNAs are a class of regulatory, non-coding small ribonucleic acid (RNA) molecules found in eukaryotes. Dysregulated expression of microRNAs can lead to downregulation or upregulation of their target gene. In general, microRNAs bind with the Argonaute protein and its interacting partners to form a silencing complex. This silencing complex binds with fully or partial complementary sequences in the 3’-UTR of their cognate target mRNAs and leads to degradation of the transcripts or translational inhibition, respectively. However, recent developments point towards the ability of these microRNAs to bind to the promoters, enhancers or coding sequences, leading to upregulation of their target genes. This review briefly summarizes the various non-canonical binding sites of microRNAs and their regulatory roles in various diseased conditions.
