Abstract: The ATP binding cassette (ABC) transporters represent the largest family of transmembrane proteins and play important roles in human inherited disease such as the multi-organ disease cystic fibrosis and cholesterol transport disorder Tangier’s disease. These proteins are also implicated in conferring multidrug resistance, rendering many cancer therapies ineffective, as well as contributing to the pathogenicity of some organisms. The yeast ABC proteins, Pdr12p, a weak acid efflux pump, and Ste6p, the a-factor exporter, were screened for interacting partners using the integrated membrane yeast two-hybrid (iMYTH) system to gain further insight into their biological function. Two interactors were identified for Ste6p, however, the Pdr12p screen identified 13 novel interactions, most notable of which are three other ABC transporters, Pdr5p, Pdr10p and Pdr11p. Subsequent functional analysis of double deletion mutants supports a genetic interaction between Pdr12p and Pdr10p as the pdr12Δ pdr10Δ strain showed resistance to increasing concentrations of weak organic acids.
