General description

Brefeldin A (BFA) is a fungal metabolite containing a 13-membered macrocyclic lactone ring. It inhibits protein and nucleic acid synthesis. BFA blocks the exchange of GDP for GTP on adenosine ribosylation factors (ARFs), thereby hindering the binding of coat protein (β-COP) and consequently 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. It demonstrates a diverse array of biological functions, including antitumor, antiviral, antibiotic, antimitotic, antifungal and antinematodal properties.

Application

Brefeldin A has been used to:



  • increase CRISPR genome editing efficiency.
  • facilitate the measurement of cytokine production
  • block intracellular transports in cell culture experiments
