Am looking for chipSEQ data available for prostate cancer. Some of the encode data includes chipSEQ but is other tissues or cell lines.

Moreover, for the chipSEQ data, is there a well accepted process to identify the motif within the peak regions; because with the chipSEQ data, I would like to first identify the peak regions (if its not already available for that dataset) and then identify the binding sites within those peak regions, because those are the important regulatory nucleotides.

Thanks!
