The miR-124 microRNA precursor is a small non-coding RNA molecule that has been identified in flies (MI0000373), nematode worms (MI0000302), mouse (MI0000150) and human (MI0000443). The mature ~21 nucleotide microRNAs are processed from hairpin precursor sequences by the Dicer enzyme, and in this case originates from the 3' arm. miR-124 has been found to be the most abundant microRNA expressed in neuronal cells. Experiments to alter expression of miR-124 in neural cells did not appear to affect differentiation.

Comments

miR-124 was cloned from mouse brain [1] and embryonic stem cells [2] by independent groups. There are 3 predicted precursor hairpin sequences: mir-124-1 (MI0000716 ) on chromosome 14, mir-124-2 (MI0000717 ) on chromosome 3, and mir-124-3 (previously known as miR-124 here, MI0000150 ) on chromosome 2. All have closely related predicted human homologues (MI0000443 , MI0000444 and MI0000445 ). Lagos-Quintana et al. also report a mature miRNA sequence miR-124b, with a G insertion at position 12 [1]. miR-124b is not found in either the mouse or human genome assemblies.
