Brefeldin A produced from Penicillium brefeldianum may be used to study protein and lipid transport between Golgi complex and the cell surface.

Biochem/physiol Actions

Brefeldin A (BFA) is a fungal metabolite which disrupts the structure and function of the Golgi apparatus. BFA is an activator of the sphingomyelin cycle. Brefeldin A-mediated apoptosis has been observed in human tumor cells.
Brefeldin A (BFA) is a fungal metabolite which disrupts the structure and function of the Golgi apparatus by inhibiting transport of proteins from ER to Golgi and inducing retrograde protein transport from the Golgi apparatus to the endoplasmic reticulum. BFA inhibits the transport of sphingomyelin to the surface of mammalian cells. The ester derivatives of BFA exhibit anti-cancer properties.
