I missed the original post in this thread, but from the included text I've
seen in the replies, you might be interested in some of the papers from Go
(Motiko Go? I'm not 100% sure on the first name). She was working on
correlations between exon-encoded parts of proteins and folding domains, and
some of her work was pretty convincing.
