Search For Your Favorite Target Gene in Expresso Database

The Expresso provides service for searching transcription factors binding to the promoter region of gene-of-your-interest (now Arabidopsis genes only).

You can enter the gene's TAIR ID in the dialog box bellow to view all the candidate transcription factors targeting this gene. You will get the putative binding motif information as well.
*Please note that these peaks are found computationally by MEME and further expert interpretation is required on the motifs.
*When motif is "None", it means that high confident target gene is taken directly from the corresponding paper and no motif analysis is performed.

E-value for motif-gene filtering:

Expresso provides regular expressions for each conserved motif along with each transcription factor and target genes. Going from regular expression to logo charts is easy and follows this simple rule: the nucleotides in bracket show all possible nucleotides for each position. If there is only one possibility for the position, no bracket would be shown.

For example, regular expression for the significant motif of PIF3 is: [GTC][CTA]CACGTG[GA][CAG]. The logo chart is shown as the image bellow. You can clearly see how conversion between logo chart and regular expression works.
