The ABC transporters are also recognized as important contributors to pharmacokinetics, especially in drug-drug interactions and adverse drug effects. Drugs and xenobiotics, as well as pathological conditions, can influence the transcription of ABC transporters, or modify their activity or intracellular localization. Kinases can affect the aforementioned processes for ABC transporters as do protein interactions. In this review, we focus on the ABC transporters ABCB1, ABCB11, ABCC1, ABCC4 and ABCG2 and illustrate how kinases and protein-protein interactions affect these transporters. The clinical relevance of these factors is currently unknown, however these examples suggest that our understanding of drug-drug interactions will benefit from further knowledge of how kinases and protein-protein interactions affect ABC transporters.}, issn = {0090-9556}, URL = {https://dmd.aspetjournals.org/content/early/2018/03/07/dmd.118.080663}, eprint = {https://dmd.aspetjournals.org/content/early/2018/03/07/dmd.118.080663.full.pdf}, journal = {Drug Metabolism and Disposition} }
