Mouse miR-138 was cloned from mouse brain tissue in [1]. There are 2 predicted hairpin precursor structures in the mouse genome, each has a closely related human homologue [2]. mir-138-1 (MIR:MI0000722) is found on mouse chromosome 8, and mir-138-2 (MIR:MI0000164, previously named mir-138 here) on chromosome 9. Kim et al. and Obernosterer et al. independently show that the mature product is a 23mer [3,4].
