I am working on a non-model organism using customised oligo micro-arrays. I want to study the regulatory elements of differentially expressed genes (DEGs) to see whether they are controlled by shared transcriptional factors. We can map the DEGs to the recently sequenced genomic sequences of this species through selecting the best BLAST hit. I want to retrieve the regulatory genomic sequences of all DEGs and predict the possible TF binding sites of all DEGs. I want to know which tool can do this. Many thanks!
