Welcome To PicTar
PicTar is an algorithm for the identification of microRNA targets. This searchable website provides details (3' UTR alignments with predicted sites, links to various public databases etc) regarding:
(1) microRNA target predictions in vertebrates (Krek et al, Nature Genetics 37:495-500 (2005))
(2) microRNA target predictions in seven Drosophila species (Grün et al, PLoS Comp. Biol. 1:e13 (2005))
(3) microRNA targets in three nematode species (Lall et al, Current Biology 16, 1-12 (2006))
(4) human microRNA targets that are not conserved but co-expressed (i.e. the microRNA and mRNA are expressed in the same tissue) (Chen and Rajewsky, Nat Genet 38, 1452-1456 (2006)) co-expressed targets
New: co-expressed human microRNA target predictions are now available
New: PicTar miRNA target site predictions for the human (hg17), mouse (mm7),
D. melanogaster (dm2) and C. elegans (ce2) genomes can be obtained from the
UCSC Genome browser via the 'tables' feature. Thanks
to the UCSC database team, especially to Hiram Clawson.
Updated predictions for human (hg18), mouse (mm9) and C. elegans (ce6) are
available on our own UCSC mirror at http://dorina.mdc-berlin.de .
For your convenience, doRiNA offers a link for downloading PicTar target site
predictions: simply run a doRiNA query
for all miRNA targets, setting the search options to 100% under step 3, and
follow the link on the top of the results page.
