Comments

The mir-322 locus appears able to express two mature miRNA sequences. Poy et al. cloned a sequence originating from the 5' arm from mouse pancreatic beta cells [2]. This sequence is orthologous to the experimentally validated miR-424 sequence from human (MIR:MI0001446), but was named miR-322-5p in [2]. The mature product from the 3' arm of this precursor sequence is the predicted mouse homologue of miR-322, experimentally verified in rat (MIR:MI0000589) [1], and later in mouse [3]. The orthologous human locus does not appear to contain the miR-322 sequence. Landgraf et al. confirm that the 5' product is the predominant one [4]. The mature sequence shown here represents the most commonly cloned form from large-scale cloning studies [4].
