In molecular biology, the microRNA miR-219 was predicted in vertebrates by conservation between human, mouse and pufferfish and cloned in pufferfish. It was later predicted and confirmed experimentally in Drosophila. Homologs of miR-219 have since been predicted or experimentally confirmed in a wide range of species, including the platyhelminth Schmidtea mediterranea, several arthropod species and a wide range of vertebrates (MIPF0000044). The hairpin precursors (represented here) are predicted based on base pairing and cross-species conservation; their extents are not known. In this case, the mature sequence is excised from the 5' arm of the hairpin. miR-219 has also been linked with NMDA receptor signalling in humans, and it has been suggested that deregulation of this miRNA can lead to the expression of mental disorders such as schizophrenia.

Comments

This human miRNA was predicted by computational methods using conservation with mouse and Fugu rubripes sequences [1]. Expression of the 5' excised miR has been validated in zebrafish, and the 5' end mapped by PCR [2]. The mature products were later validated in human [3]. Two hairpin precursor structures are predicted, mir-219-1 on chromosome 6 (MI0000296) and mir-219-2 on chromosome 9 (MI0000740) [2].
