I am searching for a protein (or transcription factor) that can interact with a short DNA sequence (that is NOT promoter or some part of promoter for another gene) and this interaction results in producing signal that control the expression of another transcription factor. Can someone suggest such a regulatory network in plants, animals or other organisms?
Hello Gi Ta.
You could start to study these papers that provide DNA element and TF binding as examples.

Cheers.
As an example of what you are looking for:
Sp1 (a transcription factor) interacts with the gene of HIF-1alfa (another transcription factor) that controls more than 100 genes.
