Application

Bafilomycin A1 has been used:
  • as an autophagy inhibitor to study its effects on hepatic steatosis in human hepatocytes[1]
  • as a vacuolar-type H+ -ATPase inhibitor to study its effects on the cell viability, percentage of PI-positive cells, and glucose-stimulated insulin secretion (GSIS) in mice INS-1 cells[2]
  • as a vacuolar-type H+ -ATPase inhibitor to study its effects on tau degradation in human SH-SY5Y cells[3]

Biochem/physiol Actions

A specific inhibitor of vacuolar type H+-ATPase (V-ATPase) in animal cells, plant cells and microorganisms.
Bafilomycin A1 inhibits autophagosome-lysosome fusion and autolysosome acidification, the steps involved in the autophagic process that is required for maintaining functional autophagic flux and cellular homeostasis.[4]
Specific inhibitor of vacuolar type H+-ATPase (V-ATPase).

Although biotherapeutics have vast potential for treating brain disorders, their use has been limited due to low exposure across the blood-brain barrier (BBB). We report that by manipulating the binding mode of an antibody fragment to the transferrin receptor (TfR)

Bafilomycin A1 is known as a strong inhibitor of the vacuolar type H(+)-ATPase in vitro, whereas other type ATPases, e.g. F1,F0-ATPase, are not affected by this antibiotic (Bowman, E.M., Siebers, A., and Altendorf, K. (1988) Proc. Natl. Acad. Sci. U.S.A.

The vacuolar H+-ATPases (V-ATPases) are conserved ATP-dependent proton pumps that acidify intracellular compartments in eukaryotic cells. The role of Cpvma1, a V-ATPase catalytic subunit A of Cryphonectria parasitica, was investigated by generating cpvma1-overexpressing and cpvma1-silenced strains. The mutant strains were

Autophagy, 11(8), 1437-1438 (2015-07-15)
Autophagosome-lysosome fusion and autolysosome acidification constitute late steps in the autophagic process necessary to maintain functional autophagic flux and cellular homeostasis. Both of these steps are disrupted by the V-ATPase inhibitor bafilomycin A1, but the mechanisms potentially linking them are
