As you mention the Genomic Hyperbrowser (Hyperbrowser is a Elixir.no project and I guess you are in Norway, if you need more help we can contact the developers directly):

Edit: There are tools that do search for TATA patterns directly, and there is a tool called Transcription factor analysis that gives you known TF's for genes of interest. There are the Motif Tools providing FIMO (need to scroll a little).

Other options:

• Motiv finder IGV: https://www.broadinstitute.org/igv/motif_finder
• In MEME suit, there is FIMO: http://meme-suite.org/tools/fimo
• there ar possibly dozens of other motif finders, most will need a PWM of the TATA box.

Another possibly better way of evidence of transcription by RNA-pol II is to check for the presence of an RNA-pol II signal in Encode data (if that is available). Note that the TATA box in the promoter is not specific to TFs, in fact most RNA-pol II transcribed mRNA has that.
