  2. Microautophagy - Wikipedia

    en.wikipedia.org/wiki/Microautophagy

    Microautophagy together with macroautophagy is necessary for nutrient recycling under starvation. Microautophagy due to degradation of lipids incorporated into vesicles regulates the composition of lysosomal/vacuolar membrane. [1] Microautophagic pathway functions also as one of the mechanism of glycogen delivery into the lysosomes. [2]

  3. Autophagy - Wikipedia

    en.wikipedia.org/wiki/Autophagy

    Microautophagy, on the other hand, involves the direct engulfment of cytoplasmic material into the lysosome. [45] This occurs by invagination, meaning the inward folding of the lysosomal membrane, or cellular protrusion.

  4. Chaperone-mediated autophagy - Wikipedia

    en.wikipedia.org/wiki/Chaperone-mediated_autophagy

    Specific selection of proteins for degradation in all forms of autophagy came to further understanding as studies discovered the role of chaperones like hsc70. Although hsc70 targets cytosolic protein to CMA based on specific amino acid sequence recognition, it works differently when targeting proteins to macro or microautophagy. [3]

  5. Cell biology - Wikipedia

    en.wikipedia.org/wiki/Cell_biology

    In micro autophagy, the lysosome or vacuole engulfs a piece of the cytoplasm by invaginating or protruding the lysosomal membrane to enclose the cytosol or organelles. The chaperone-mediated autophagy (CMA) protein quality assurance by digesting oxidized and altered proteins under stressful circumstances and supplying amino acids through ...

  6. Autophagosome - Wikipedia

    en.wikipedia.org/wiki/Autophagosome

    The autophagic process is divided into five distinct stages: Initiation, phagophore nucleation, autophagosomal formation (elongation), autophagosome-lysosome fusion (autophagolysosome) and cargo degradation.

  7. Autophagia - Wikipedia

    en.wikipedia.org/wiki/Autophagia

    Autophagia is the practice of biting/consuming one's body. It is a sub category of self-injurious behavior (SIB). [1] Commonly, it manifests in humans as nail biting and hair pulling.

  8. ATG7 - Wikipedia

    en.wikipedia.org/wiki/ATG7

    Autophagy related 7 is a protein in humans encoded by ATG7 gene. [5] [6] Related to GSA7; APG7L; APG7-LIKE.[6]ATG 7, present in both plant and animal genomes, acts as an essential protein for cell degradation and its recycling.

  9. Chaperone-assisted selective autophagy - Wikipedia

    en.wikipedia.org/wiki/Chaperone-assisted...

    Proteins that are degraded by chaperone-assisted selective autophagy include pathogenic forms of the Huntingtin protein, which cause Huntington's disease. [4] Furthermore, the expression of the cochaperone BAG3 is upregulated in aged neuronal cells, which correlates with an increased necessity to dispose oxidatively damaged proteins through autophagy.
