Welcome to the Human Transmembrane Proteome database
The Human Transmembrane Proteome database and web service are comprehensive resources of the α-helical human transmembrane proteins. It contains topology and structure information about the human α-helical transmembrane proteins classified into reliability levels. First level is proteins with known 3D structures, second level is proteins with experimentally established topology, third level is proteins with conservatively appearing domains or motifs on one side of the membrane, fourth is proteins proved to be exists, and the last level contains proteins predicted from the annotated human genome database.
You can read more about the database in the descriptive article or in the database manual.
