Sample Plots

The first two plots here show transmembrane proteins, and the second two plots show exterior proteins. Transmembrane proteins are indicated by many wide regions of positive hydropathy, and exterior proteins are indicated by many wide regions of negative hydropathy. However, almost any sequence will show both hydrophobic and hydrophilic areas.

Rhodopsin (link)

This plot shows that rhodopsin has several wide regions of positive hydropathy, which indicates that this is a transmembrane protein.

Aquaporin (link)

This plot shows that aquaphorin has one wide region of positive hydropathy near the end of its short sequence, which indicates that this is a transmembrane protein.

Microglobulin (link)

This plot shows that microglobulin has an average negative hydropathy for most of its length (with one small hydrophobic region), which indicates that this is an exterior protein.

Sialophorin (link)

This plot shows that sialophorin has an average negative hydropathy for most of its length (with one small hydrophobic region), which indicates that this is an exterior protein.
