Cytoplasm-to-vacuole targeting cvt pathway
WebJan 30, 2012 · Autophagosomes are double-membrane vesicles characteristic of macroautophagy, a degradative pathway for cytoplasmic material and organelles … Cytoplasm-to-vacuole targeting (Cvt) is an autophagy-related pathway in yeast. Under vegetative conditions it delivers hydrolases, such as aminopeptidase 1 (Ape1), to the vacuole. This makes the cvt pathway the only known biosynthetic pathway to utilize the machinery of autophagy for operation.
