  1. (a) For each known regulatory element, we show the best k-mer, its rank within the set of 284 highest scoring k-mers, the median distance to ATG (for occurrences upstream of genes within the conserved set), the optimal window, the orientation bias, the corrected ratio of upstream/coding bias, the total (upregulated/downregulated) number of microarray conditions in which the k-mer was found (see Materials and methods), TRANSFAC matches, and the best GO enrichment. (b) Novel predicted regulatory elements. k-mers shown here were selected from the list of 284 highest-scoring k-mers based on their short median distance to ATG, short optimal window, significant orientation bias, strong over-representation ratio (U/C), presence in upstream regions of over/underexpressed genes in several microarray conditions, palindromicity or resemblance to known sites in other species.
