This text is a summary paragraph taken from the Wikipedia
entry entitled mir-103/107_microRNA_precursor. 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.

The miR-103 microRNA precursor (homologous to miR-107), is a short non-coding RNA gene involved in gene regulation. miR-103 and miR-107 have now been predicted or experimentally confirmed in human.
microRNAs are transcribed as ~70 nucleotide precursors and subsequently processed by the Dicer enzyme to give a ~22 nucleotide product. In this case the mature sequence comes from the 5' arm of the precursor. The mature products are thought to have regulatory roles through complementarity to mRNA.
mir-103 and mir-107 were noted as being upregulated in obese mice and were subsequently found to have a key role in insulin sensitivity. This led to a suggestion that these microRNAs represent potential targets for the treatment of type 2 diabetes.
mir-103 has also been linked with chronic pain and intestinal cell proliferation.
