MacVector does do this (I'm not saying that it does it well, but it has
the ability). I think that the newer versions ship with a transcription
factor subsequence file that has over 600 sites bound by proteins in
promoter regions. You just have to do a nucleic acid subsequence search.
I ran a test against the junD promoter and it found all the sites that had
been mapped by Shaul etal when they cloned it (except the TATA box. I'm
not sure why it didn't find that as one of the subsequences is exactly the
same sequence as the tata box in the junD promoter. Sometimes the exact
base that the site starts at are off by 1 or two, but that's more
dependant on what you call a binding site rather than the prgms ability to
recognize it as one.
