The miR-19 microRNA precursor is a small non-coding RNA molecule that regulates gene expression. Within the human and mouse genome there are three copies of this microRNA that are processed from multiple predicted precursor hairpins:[1][2] [3]
miR-19 has now been predicted or experimentally confirmed in a wide range of vertebrate species (MIPF0000011). In this case the mature sequence is excised from the 3' arm of the hairpin precursor.
Targets of miR-19
[edit]It has been shown that the 3' UTR of the ATXN1 gene contains 3 target sites for miR-19, and that this microRNA shows moderate down regulation of reporter genes containing the ATXN1 3' UTR. ATXN1 is also regulated by miR-101, and miR-130.[4]
