The mir-34 microRNA precursor family are non-coding RNA molecules that, in mammals, give rise to three major mature miRNAs. The miR-34 family members were discovered computationally and later verified experimentally. The precursor miRNA stem-loop is processed in the cytoplasm of the cell, with the predominant miR-34 mature sequence excised from the 5' arm of the hairpin. The mature miR-34a is a part of the p53 tumor suppressor network; therefore, it is hypothesized that miR-34 dysregulation is involved in the development of some cancers.

Houbaviy et al. cloned 3 closely related sequences from mouse embryonic stem cells [1], and named them miR-34a, miR-34b and miR-172. These names have been remapped to miR-34c (MI0000403), miR-34b (MI0000404) and miR-34a (MI0000584) to clarify homology with human sequences. The predominant mature miRNA in human is expressed from the 3' arm (in contrast to previous annotation) [2]. Both arms express mature products in mouse.
