miRNA Entry for MI0002015

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.

In molecular biology, miR-148 is a microRNA whose expression has been demonstrated in human (MI0000253), mouse (MI0000550), rat (MI0000616) and zebrafish (MI0002015). miR-148 has also been predicted in chicken (MI0001189). These predicted hairpin precursor sequence are related to those of miR-152, which has been expressed in mouse (MI0000174) and is predicted in human (MI0000462). 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 3' arm of the hairpin.

Targets of miR-148

MicroRNAs act by lowering the expression of genes by binding to target sites in the 3' UTR of the mRNAs. However recently it was shown by Duursma and colleagues that miR-148 down regulates Dnmt3b by binding to a region in the protein coding region.^[4]
