Product Details

Tunicamycin | ER stress inducer

Tunicamycin (11089-65-9) is a fermentation product from Streptomyces lysosuperificus.  Provided as a mixture of tunicamycin A (C14), B (C15), C (C16) and D (C17) homologs varying in the number of carbon atoms in the fatty acid chain.   The structure shown is for tunicamycin B (the C15 homolog).  Tunicamycin is a potent inhibitor of GlcNAc phosphotransferase which thereby inhibits glycoprotein biosynthesis.1 Causes endoplasmic reticulum stress-induced autophagy2 and unfolded protein response3. Tunicamycin arrests cell cycle in late G1.4
