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: human, D. melanogaster, and C. elegans microRNA target predictions are now a track of the UCSC Genome browser. Thus, bulk downloads can be done directly from the UCSC database (use the Table Browser). Thanks to the UCSC database team, especially to Hiram Clawson.
