status: NEW40 Baculovirus transfer vectors were constructed by using the human MDR1 cDNA encoding a protein with the following mutants: S661A, S667A, and S671A (3A); S661E, S667E, and S671E (3E); S660A, S661A, S667A, T668A, S671A, S675A, S683A, and T684A (8A); and S660E, S661E, S667E, T668E, S671E, S675E, S683E, and T684E (8E), as described earlier (22, 32).

We measured whole cell swelling-activated Cl-currents (ICl,swell) in parental cells and cells expressing wild-type MDR1 or a phosphorylation-defective mutant (Ser-661, Ser-667, and Ser-671 replaced by Ala).

ABCB1 p.Ser671Ala 9950764:12:181
status: NEW50 Site-directed mutagenesis was used to substitute Ser-661, Ser-667, and Ser-671 with Ala, and both MDR1 and MDR1-3SA contain six histidine residues at the COOH-terminal end.

ABCB1 p.Ser671Ala 9950764:50:71
status: NEW143 In summary, PKA and PKC stimulation produced distinct effects on ICl,swell, and these effects were abolished by replacing Ser-661, Ser-667, and Ser-671 with Ala residues.

The mutagenic oligonucleotides were: 5Ј-TTCAAGATCCGCGCTAATAAGAA-3Ј (Ser [661] to Ala), 5Ј-AAGAAAAAGAGCCACTCGT- AGG-3Ј (Ser667 to Ala), and 5Ј-ACTCGTAGAGCGG- TCCGTGGATC-3Ј (Ser671 to Ala).
