OPM Browser

The OPM browser organizes membrane associated proteins by their spatial arrangements with respect to membrane's lipid bilayer. The classification is based on the  Orientations of Proteins in Membranes (OPM) database (Andrei Lomize, University of Michigan) and UniProt.

Here you can browse through protein entities in the PDB based on their membrane association.
