The miR-129 microRNA precursor is a small non-coding RNA molecule that regulates gene expression. This microRNA was first experimentally characterised in mouse and homologues have since been discovered in several other species, such as humans, rats and zebrafish. The mature sequence is excised by the Dicer enzyme from the 5' arm of the hairpin. It was elucidated by Calin et al. that miR-129-1 is located in a fragile site region of the human genome near a specific site, FRA7H in chromosome 7q32, which is a site commonly deleted in many cancers. miR-129-2 is located in 11p11.2.

The miRNA from the 5' arm of this precursor was verified by cloning in mouse [1]. Reference [2] named the human/mouse conserved sequence miR-129b, but subsequent genome searches suggest that the same mature sequence may be expressed from two predicted hairpin precursors in both mouse (this entry and MI0000222) and human (MI0000252 and MI0000473). Poy et al. independently cloned a mature miRNA from the 3' arm of the precursor, called mmu-miR-129-3p [3]. This sequence is not perfectly conserved in the other predicted mouse miR-129 precursor (MI0000222). The mature sequence shown here represents the most commonly cloned form from large-scale cloning studies [4].
