General description

Patulin is a mycotoxin produced by a variety of molds, such as, Aspergillus and Penicillium. It is commonly found in apples. It is used as an inhibitor of potassium uptake and as an inducer of ion flux across cell membranes, potentially involving Na+-K+ dependent ATPase and to induce intra- and intermolecular protein crosslinking.

Application

Patulin has been used:
  • to study patulin contamination of bottled wine
  • in DNA-damaging activity of patulin in Escherichia coli
  • in molecular cloning and functional characterization of two CYP619 cytochrome P450s involved in biosynthesis of patulin in Aspergillus clavatus

Biochem/physiol Actions

Mycotoxin with anti-bacterial, potassium uptake inhibitory, and possibly carcinogenic activities. It is used as an inhibitor of potassium uptake and as an inducer of ion flux across cell membranes, potentially involving Na+-K+ dependent ATPase and to induce intra- and intermolecular protein crosslinking.

Drug screening is often limited to cell-free assays involving purified enzymes, but it is arguably best applied against systems that represent disease states or complex physiological cellular networks. Here, we describe a high-content, cell-based drug discovery platform based on phosphospecific
