Multidrug Transporter ABCG2 is a <scene name='83/832937/Dimer/1'>dimer</scene> that consists of two cavities seperated by a <scene name='83/832937/Leucine_plug/1'>leucine plug</scene>. 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 <scene name='83/832937/Atp_and_mg_bound_to_abcg2/1'>magnesium ion and ATP</scene> are bound. Its inter- and intra-disulfides promote the release of the substrate from the cavity into the extracellular space.
