Description
The miRNA track shows microRNAs from
miRBase.
Display Conventions and Configuration
Mature miRNAs (miRs) are represented by
thick blocks. The predicted stem-loop portions of the primary transcripts
are indicated by thinner blocks. 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.
To display only those items that exceed a specific unnormalized score, enter
a minimum score between 0 and 1000 in the text box at the top of the track
description page.
Methods
Mature and precursor miRNAs from the miRNA Registry were
aligned against the genome using blat.
The extents of the precursor sequences were not generally known, and were
predicted based on base-paired hairpin structure.
miRBase is described in Griffiths-Jones, S. et al. (2006).
The miRNA Registry is
described in Griffiths-Jones, S. (2004) and Weber, M.J. (2005) in the
