miRNA Entry for MI0016609

This text is a summary paragraph taken from the Wikipedia entry entitled mir-156_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.

MicroRNA (miRNA) precursor mir-156 is a family of plant non-coding RNA. This microRNA has now been predicted or experimentally confirmed in a range of plant species (MIPF0000008). Animal miRNAs are transcribed as ~70 nucleotide precursors and subsequently processed by the Dicer enzyme to give a ~22 nucleotide product. In plants the precursor sequences may be longer, and the carpel factory (caf) enzyme appears to be involved in processing. In this case the mature sequence comes from the 5' arm of the precursor, and both Arabidopsis thaliana and rice genomes contain a number of related miRNA precursors which give rise to almost identical mature sequences. The extents of the hairpin precursors are not generally known and are estimated based on hairpin prediction. The products are thought to have regulatory roles through complementarity to mRNA.
