The miR-124 microRNA precursor is a small non-coding RNA molecule that has been identified in flies (MI0000373),[1] nematode worms (MI0000302),[2] mouse (MI0000150) and human (MI0000443).[3] 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.[4]

[edit] Targets of miR-124

  • Visvanathan et al. showed that miR-124 targets the mRNA of the anti-neural function protein SCP1 (small C-terminal domain phosphatase 1).[5]
