I have the location information of TFBS and enhancer such as: chr1:851083-852146, and I would like to know the distribution of known TFBS on a specific enhancer. Whether UCSC Genome Browser can help me to identify it?
The UCSC Genome Browser does not offer a TFBS track, to my knowledge.
You could use FIMO to call TFBS on your reference genome, against a database like JASPAR. Or TRANSFAC, if you have a license.
Once you have TFBS in BED format, you could use BEDOPSbedmap to count or call TF hits from your FIMO scan that associate (overlap with) your regions of interest, such as your enhancer, or any number of other sites in BED format.
