The most likely explanation involves lncRNA-0021 functioning as a competitive endogenous RNA (ceRNA) that dynamically sequesters mmu-miR-6361 from its primary mRNA targets rather than forming static binding complexes. In this model, lncRNA-0021 contains multiple imperfect binding sites with varying affinities for mmu-miR-6361, creating a buffering system that modulates miRNA bioavailability in response to cellular conditions. The binding specificity emerges from kinetic competition rather than thermodynamic stability - lncRNA-0021 acts as a molecular sponge with fast association/dissociation rates that allow preferential capture of mmu-miR-6361 over other miRNAs sharing similar seed sequences. This mechanism predicts that lncRNA-0021 expression levels will inversely correlate with mmu-miR-6361 target gene repression, and that the regulatory effect will be most pronounced when miRNA concentrations are limiting. The ceRNA function would be particularly relevant in neuronal contexts where precise miRNA dosage controls synaptic plasticity and neurodevelopmental processes.
