The miRNA track shows microRNAs from the miRNA Registry at the Wellcome Trust Sanger Institute. Mature miRNAs (miRs) are represented by thick lines; the predicted stem-loop portions of the primary transcripts are indicated by thinner lines. miRNAs in the sense orientation are shown in black; those in the reverse orientation are colored grey. When a single precursor produces two mature miRs from its 5' and 3' parts, it is displayed twice with the two different positions of the mature miR.
Mature and precursor miRNAs from the miRNA Registry are aligned against the genome using blat. The extents of the precursor sequences are not generally known, and are predicted based on base-paired hairpin structure. The miRNA Registry is described in Griffiths-Jones S (2004), The microRNA Registry, Nucl. Acids Res. 32:D109-D111.
This track was created by Michel Weber of Laboratoire de Biologie Moléculaire Eucaryote, CNRS Université Paul Sabatier (Toulouse, France) and Sam Griffiths-Jones of The Wellcome Trust Sanger Institute (Cambridge, UK).
