Search promoters for a gene or a list of genes by gene name, GenBank ID or chromosome location (Figure 1). The resulting page contains all annotated promoters for the gene, ranked from the highest quality to the lowest. Links for gene information and promoter information (including localization of transcription factor binding sites) are provided by the hotlinks in ‘Gene ID’ and ‘Promoter ID’ columns, respectively (see Figure 1). Sequence retrieval of desired promoters can be achieved by checking the box on the left of each entry. Sequence length for retrieval can be decided by users, with the default being 1 kb (700 bp upstream and 299 bp downstream of TSS). Promoter sequences of interest can also be conveniently sent to ‘on-the-fly analysis’ page for further analysis (see below).
