Epidermolytic toxin from Staphylococcus aureus binds to filaggrins.
The affinity of epidermolytic toxin from Staphylococcus aureus for proteins from the target tissue has been tested by a Western blotting procedure. Particular proteins in a 1 M phosphate extract of epidermis reacted on nitrocellulose blots with a probe prepared by the conjugation of toxin with peroxidase. Protein extracted into 50 mM Tris-HCl did not react. The probe detected profilaggrin, filaggrin and a smaller unidentified polypeptide. It is suggested that the interaction is relevant to the mode of action of the toxin.
