The miRNA track shows microRNAs from
Display Conventions and Configuration
The precursor forms of
microRNAs (mirs) in the sense
orientation are shown in black; those in the reverse orientation are colored
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. For this track, a score of 960 signifies that the miRNA is on the + strand and a
score of 480 signifies that it is on the - strand.
Precursor miRNA genomic locations from
were calculated using wublastn for sequence alignment with the requirement of
100% identity. 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
