In recent times, microRNA ( miRNA ) have emerged as primary regulators of fundamental biological processes including cellular differentiation, proliferation, apoptosis, as well as synaptic plasticity. However, miRNAs bind their targets with only partial complementarity, making it very challenging to determine exactly how a miRNA is functioning in specific biological environments. This review discusses key principles of miRNA target recognition and function which have emerged through the progressive advancement of biological and bioinformatics approaches. Ultimately, the integration of gene expression and biochemical methods with sequence‐ and systems‐based bioinformatics approaches will reveal profound insights regarding the importance of target contextual features in determining miRNA target recognition and regulatory outcome, as well as the importance of RNA interaction networks in enabling miRNA to regulate different target genes and functions in specific biological contexts. There is therefore a demand for the elegant design of future experiments such that principles of context‐specific miRNA target recognition and regulatory outcome can be accurately modeled in normal developmental and disease states.
