| Protein Function |
Translocates drugs and phospholipids across the membrane (PubMed:8898203, PubMed:2897240, PubMed:9038218). Catalyzes the flop of phospholipids from the cytoplasmic to the exoplasmic leaflet of the apical membrane. Participates mainly to the flop of phosphatidylcholine, phosphatidylethanolamine, beta-D-glucosylceramides and sphingomyelins (PubMed:8898203). Energy-dependent efflux pump responsible for decreased drug accumulation in multidrug-resistant cells (PubMed:2897240, PubMed:9038218).

| Recommended Action | |||||||||
|---|---|---|---|---|---|---|---|---|---|
| Management | Until further information is available, caution is recommended if binimetinib must be used concomitantly with P-gp, UGT 1A1, UGT 2B7, and/or BCRP inhibitors. Binimetinib should be monitored more closely whenever a P-gp, UGT 1A1, UGT 2B7, and/or BCRP inhibitor is added to or withdrawn from therapy, and the binimetinib dosage adjusted as necessary. | ||||||||
