The cytoplasm and vacuole of cells are two very important organelles, designed to carry out many biological cell functions. The cytoplasm of a cell fills the interior spaces of a cell and is responsible for holding organelles in place, protecting the cell and is where many biochemical interactions occur-including transport, and protein folding.

Autophagy degrades damaged organelles, cell membranes and proteins, and insufficient autophagy is thought to be one of the main reasons for the accumulation of damaged cells and aging. [87] Autophagy and autophagy regulators are involved in response to lysosomal damage, often directed by galectins such as galectin-3 and galectin-8.
The formation of autophagosomes is regulated by genes that are well-conserved from yeast to higher eukaryotes. The nomenclature of these genes has differed from paper to paper, but it has been simplified in recent years. The gene families formerly known as APG, AUT, CVT, GSA, PAZ, and PDD are now unified as the ATG (AuTophaGy related) family. [4]
Autophagy (from Greek words for "self" and "eating") is a process of digesting or degrading cytoplasmic molecules (proteins, lipids, sugars and organelles). Macroautophagy is the main autophagic pathway, used primarily to eradicate damaged cell organelles such as mitochondria , [ 6 ] ribosomes, etc., which helps in supplying amino acids and ...
PCD serves fundamental functions during both plant and animal tissue development. Apoptosis and autophagy are both forms of programmed cell death. [4] Necrosis is the death of a cell caused by external factors such as trauma or infection and occurs in several different forms.
Autophagy database(s) aim to provide a comprehensive list of autophagy-related genes and proteins, whether they are identified as orthologs or homologs of other, potentially related, proteins. Many kinds of information, including sequences, functions, and 3D structures, can be stored, thus making them accessible in a searchable format.
Autophagy is an important cellular process that helps in maintaining homeostasis. It goes through destroying and recycling the cytoplasmic organelles and macromolecules. During the initiation of autophagy, ATG7 acts like an E-1 enzyme for ubiquitin-like proteins (UBL) such as ATG12 and ATG8. ATG7 helps these UBL proteins in targeting their ...
Autophagy is the process by which endogenous proteins and damaged organelles are destroyed intracellularly. Autophagy is postulated to be essential for cell homeostasis and cell remodeling during differentiation, metamorphosis, non-apoptotic cell death, and aging. Reduced levels of autophagy have been described in some malignant tumors, and a ...
