Thanks for your question Target mimicry is a common method to study the function of miRNA. There is a non-coding protein gene IPS in Arabidopsis, and its transcription RNA can specifically bind to miRNA through sequence complementarity, but it forms incomplete complementary bubble structure at the cleavage site of miRNA, that is, miRNA cannot cleavage IPS RNA, thus inhibiting the degradation of miRNA to its target gene mRNA. IPS gene is equivalent to the target mimicry. (Franco-Zorrilla et al., 2007) 2 1
