Functional analysis of ABCA8, a new drug transporter.
Tsuruoka S., Ishibashi K., Yamamoto H., Wakaumi M., Suzuki M., Schwartz G.J., Imai M., Fujimura A.
We examined the transport capacity in Xenopus laevis oocytes of human EST KIAA0822/ABCA8, a member of the ABC superfamily. Substrates of ABCC2/MRP-2 such as [14C]estradiol-beta-glucuronide, taurocholate, and LTC4, and of organic anion transporter (OAT), such as para-aminohippuric acid, ochratoxin- ... >> More
We examined the transport capacity in Xenopus laevis oocytes of human EST KIAA0822/ABCA8, a member of the ABC superfamily. Substrates of ABCC2/MRP-2 such as [14C]estradiol-beta-glucuronide, taurocholate, and LTC4, and of organic anion transporter (OAT), such as para-aminohippuric acid, ochratoxin-A, were significantly accumulated while tetraethylammonium and doxorubicin were not. The transport of [14C]estradiol-beta-glucuronide was ATP-dependent and K(m) and V(max) values of 30.4microM and 66.9pmol/h/egg, respectively, were estimated. The transport of [14C]estradiol-beta-glucuronide was inhibited by substrates/inhibitors of ABCC2/MRP-2, but not by those of the organic cation transporter and multidrug resistance protein (MDR)-1. KIAA0822/ABCA8 possesses two ATP-binding sites and fourteen transmembrane domains. Northern blot analysis revealed expression in most organs, especially in heart, skeletal muscle, and liver. Thus, ABCA8 is a new member of the xenobiotic transporter ABC-subfamily. << Less
