This text is a summary paragraph taken from the Wikipedia
entry entitled mir-219_microRNA_precursor_family. miRBase and Rfam
are facilitating community annotation of microRNA families and entries in Wikipedia. Read more ...
The text in this section is taken from the free, online
encyclopedia, Wikipedia. Anyone can edit a Wikipedia page. We hope
that experts on particular microRNA sequences will use the links to
Wikipedia below to edit the annotation of individual microRNAs, to add
information about function, evolution, discovery, and literature
references, for example. Any changes that you make will be visible in
Wikipedia immediately, and in miRBase within 24 hours.
Editing Wikipedia entries is straightforward. If you haven't
edited a page before, you might like to take a look at the following
Wikipedia help pages:
You can also create new pages at Wikipedia about microRNA families
that do not currently have specific entries there. Please let us know
if you do, so we can incorporate your annotation into miRBase, and
create the appropriate links from miRBase entries to the relevant
Wikipedia pages.
Please note, we're not responsible for the content of Wikipedia pages.
You can read more about miRBase, Wikipedia and community annotation on this blog post.

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.

In molecular biology, the microRNA miR-219 was predicted in vertebrates by conservation between human, mouse and pufferfish and cloned in pufferfish.[1] It was later predicted and confirmed experimentally in Drosophila.[2] 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.[3]
