Mutations in TM9 (I837L and N839I) or in TM6 (G388A and A339P) resulted in similar drug resistance profiles with four structurally different drugs (increased resistance to vincristine or actinomycin D but decreased resistance to colchicine or daunorubicin relative to wild-type P-gp).

Although mutation of only one of these residues (L975A, V981A and F983A) has no effect on the phenotype of the protein [20], double mutations either completely inhibit (V981A/F983A and L975A/V981A) or cause 50% inhibition (L975A/F983A) of Table 1.
