The Membrane Yeast Two-Hybrid (MYTH) technology was used in this study to find protein-protein interactors of Saccharomyces cerevisiae ATP binding cassette (ABC) transporters Nft1p, Pdr10p, Pdr18p and Vmr1p. There were 23 interactors for Nft1p, 22 interactors for Pdr10p, 4 interactors for Pdr18p and 1 interactor for Vmr1p. The 43 unique interactors belong to a wide variety of functional categories. There were 11 interactors involved in metabolism, 9 interactors involved in transport, 8 interactors with unknown function, 4 interactors involved in trafficking and secretion, 3 interactors involved in protein folding, 2 interactors involved in stress response, and 1 interactor in each of the following categories: cell wall assembly, cytoskeleton maintenance, nuclear function, protein degradation, protein modification and protein synthesis. Follow up experiments also showed that Pdr15p and Pdr18p play an important role in zinc homeostasis because deletion of these ABC transporters results in sensitivity to zinc shock.
