Fig. 5. SIS3 stimulates vanadate-sensitive ATPase activity of ABCB1 and ABCG2.

Fig. 5.

The effect of SIS3 (0 – 5 μM) on vanadate-sensitive (A) ABCB1 and (B) ABCG2 ATP hydrolysis was determined by endpoint Pi assay, as described previously [1, 67]. Values are presented as mean ± S.D. calculated from three independent experiments.
