miR-130 appears to be vertebrate-specific miRNA and has now been predicted or experimentally confirmed in a range of vertebrate species (MIPF0000034). Mature microRNAs are processed from the precursor stem-loop by the Dicer enzyme.
miR-130 seems to be a specific type of microRNA that is exclusive to vertebrates and has been found in multiple vertebrate species (MIPF0000034). It is produced by the Dicer enzyme from its precursor stem-loop structure.
