Abstract


A significant portion of clinically observed antifungal resistance is mediated by ATP-binding cassette (ABC) and major facilitator superfamily (MFS) transport pumps that reside in the plasma membrane. We review the mechanisms responsible for this phenomenon. Hyper resistance is often brought about by several kinds of DNA amplification or by gain-of-function mutations in a variety of transcription factors. Both of these result in overexpression of ABC and MFS transporters. Recently, however, several additional modes of resistance have been observed. These include mutations in non-conserved nucleotides leading to altered mRNA stability and a mutation in yeast transporter Pdr5, which improves cooperativity between drug-binding sites.
