ABCG2 is a homodimer with each dimer containing two domains, the nucleotide binding domain (NBD) and the transmembrane domain. The NDB is located inside of the cell while the transmembrane domain is located in the cell membrane. [[Image:membrane domains.png|200 px|right|thumb|Figure 1.

As an [https://en.wikipedia.org/wiki/ATP-binding_cassette_transporter ABC Transporter], ABCG2 exhibits ATPase activity in which it binds and hydrolyzes ATP in order to cultivate the energy needed for the transport of molecules across the cell membrane. Two molecules of ATP bind the
