Hello everybody,

I am trying to create a dataset of signal anchor proteins of the type II. These are proteins which posses a signal peptide but which will be retained in the ER membrane due to a lacking cleavage site. I have already done some SRS searches on SwissProt and applied some own parsers. But apparently there are not that many proteins with a high confidence for being a real signal anchor ;-(

Does anybody of you know a database where I could find these kind of proteins? Or even better, does anybody work on this subject and like to help me out a bit?

Thank you very much in advance,
cu
