Cavity 1 is a binding pocket open to the cytoplasm and the inner leaflet of the plasma membrane. Its shape is suitable to bind flat, hydrophobic and polycyclic substrates. Many of its amino acids residues form hydrophobic interactions with the bound substrate, as shown in green in Figure 1. Cavity 2 is located above the leucine plug. It is empty until a are bound to ABCG2. Its promote the release of the substrate from the cavity into the extracellular space.
