1 Hitherto three variant forms of ABCG2 have been documented on the basis of their amino acid moieties (i.e., Arg, Gly, and Thr) at the position 482. Glycine ATP binding cassette subfamily G member 2 (Junior blood group) Homo sapiens
2 The ATPase activity of the plasma membrane expressing ABCG2 (Gly-482) was significantly enhanced by prazosin. Glycine ATP binding cassette subfamily G member 2 (Junior blood group) Homo sapiens
3 In contrast, ABCG2 (Arg-482) transports [(3)H]methotrexate in an ATP-dependent manner; however, no transport activity was observed with the other variants (Gly-482 and Thr-482). Glycine ATP binding cassette subfamily G member 2 (Junior blood group) Homo sapiens
