Application Brefeldin A is produced from Penicillium brefeldianum and is used to study protein transport. Biochem/physiol Actions 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. 1 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. BFA is an activator of the sphingomyelin cycle. Brefeldin A-mediated apoptosis has been observed in human tumor cells.
