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 has been shown to increase CRISPR-mediated homology-directed repair (HDR) efficiency.
