Mir-2 microRNA precursor (original) (raw)

The mir-2 microRNA family includes the microRNA genes mir-2 and mir-13 (MIPF0000049). Mir-2 is widespread in invertebrates, and it is the largest family of microRNAs in the model species Drosophila melanogaster. MicroRNAs from this family are produced from the 3' arm of the precursor hairpin. Leaman et al. showed that the miR-2 family regulates cell survival by translational repression of proapoptotic factors. Based on computational prediction of targets, a role in neural development and maintenance has been suggested.
