Are there any specialist transmembrane protein databases?

Question

[Good Gravy]

I am working almost exclusively with transmembrane proteins. Are there any databases that specialise in categorising transmembrane proteins. For example by membrane type, number of membrane spanning regions, number of non-polar helices, whether the protein is functional or structural, et cetera.

just uniprot ? see How To Retrive A Batch Of Transmembrane Domains From Uniprot?

UniProt is showing a lot of hits. I might make this a separate question, but doesn't uniprot automatically determine transmembrane regions? i.e its unreviewed and should be treated sceptically.

I was trying to pull some memories up from apparently archived brain cells, and I remembered the IUPHAR classification folks had one. I went to look, and the one I remembered is apparently not maintained anymore: http://www.iuphar-db.org/index.jsp

But their new site might be of some use: http://www.guidetopharmacology.org/ Doesn't appear to have the detail you need though.
