Annotation confidence High
Do you think this miRNA is real?
Mouse miR-19b was cloned from mouse tissues by independent groups [1,2]. There are two predicted hairpin precursors, with closely related human homologues [4]: mir-19b-1 (MIR:MI0000718) on chromosome 14, and mir-19b-2 (previously named mir-19b here, MIR:MI0000546) on mouse chromosome X.
