Annotation confidence Not enough data
Do you think this miRNA is real?
Reference [1] described the discovery of MIR159b, but referred to the sequence by the internal identifier MIR40b. This sequence is not related to C. elegans miR-40. MIR159b is found on chromosome 1 in Arabidopsis thaliana [2] and is thought to target mRNAs coding for MYB proteins which are known to bind to the promoter of the floral meristem identity gene LEAFY [3].
