General description

Brefeldin induces ADP-ribosylation of CtBP1/BARS protein that regulates the intracellular trafficking and movement of secretory proteins from endoplasmic reticulum to Golgi apparatus.
Chemical structure: macrolide

Application

Suitable for molecular biology studies of secretory proteins and mechanisms of intracellular transport

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.

Principle

Brefeldin is a fungal metabolite that disrupts protein secretion in eukaryotic cells by disrupting the Golgi apparatus. It does not affect the process of protein synthesis.

The signal transducer and activator of transcription (STAT) family of transcription factors orchestrate hematopoietic cell differentiation. Recently, mutations in STAT1, STAT5B, and STAT3 have been linked to development of immunodysregulation polyendocrinopathy enteropathy X-linked-like syndrome. Here, we immunologically characterized 3 patients
