miRNA
Small, ~22-nt, RNA molecule that is the endogenous transcript of a miRNA gene (or the product of other non coding RNA genes). Micro RNAs are produced from precursor molecules (SO:0001244) that can form local hairpin structures, which ordinarily are processed (usually via the Dicer pathway) such that a single miRNA molecule accumulates from one arm of a hairpin precursor molecule. Micro RNAs may trigger the cleavage of their target molecules or act as translational repressors.
