Do you think this miRNA is real?
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 (MIR:MI0000716) on chromosome 14, mir-124-2 (MIR:MI0000717) on chromosome 3, and mir-124-3 (previously known as miR-124 here, MIR:MI0000150) on chromosome 2. All have closely related predicted human homologues (MIR:MI0000443, MIR:MI0000444 and MIR: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.
