Membrane Protein Explorer (MPEx), a tool for exploring the topology and other features of membrane proteins by means of hydropathy plots based upon thermodynamic principles. Click on the Java applet button at right to start MPEx. For instructions, see Features at a Glance and Brief Instructions for MPEx below, or the full documentation. Current version: 3.0. MPEx can also be installed on your computer as a Web Start application. A useful adjunct to MPEx is MPtopo, a database of Membrane Protein topology accessible from MPEx.
The Web Start application (see just above) offers all of the advantages of the old standalone installation, plus automatic updates.
