Annotation confidence Not enough data
Do you think this miRNA is real?
This sequence was independently identified by two groups. Park et al. described miR172a1, found on chromosome 2 in Arabidopsis thaliana and thought to target mRNAs coding for Apetala 2 (AP2) proteins, and miR172a2 (MIR:MI0000216) [1]. These sequences have been renamed miR172a and miR172b here to match previous plant miRNA nomenclature. This sequence was referred to by Mette et al. by the internal identifier MIR123a [2], and was previously identified as MIR180a here. This sequence is not related to mouse miR-123.
