An autophagosome is a spherical structure with double layer membranes. [2] It is the key structure in macroautophagy , the intracellular degradation system for cytoplasmic contents (e.g., abnormal intracellular proteins , excess or damaged organelles , invading microorganisms).
Microtubule-associated proteins 1A/1B light chain 3B (hereafter referred to as LC3) is a protein that in humans is encoded by the MAP1LC3B gene. [5] LC3 is a central protein in the autophagy pathway where it functions in autophagy substrate selection and autophagosome biogenesis. LC3 is the most widely used marker of autophagosomes. [6]
Autophagy protein 5 (ATG5) is a protein that, in humans, is encoded by the ATG5 gene located on chromosome 6.It is an E3 ubi autophagic cell death.ATG5 is a key protein involved in the extension of the phagophoric membrane in autophagic vesicles.
ATG may be part of the protein name (such as ATG7) or part of the gene name (such as ATG7), [53] although all ATG proteins and genes do not follow this pattern (such as ULK1). [ 52 ] To give specific examples, the UKL1 enzyme (kinase complex) induces autophagosome biogenesis, and ATG13 ( Autophagy-related protein 13 ) is required for phagosome ...
The Atg1 gene lies on chromosome VII of S. cerevisiae. The encoded protein with a mass of 101.7 kDa has a length of 897 amino acids and includes a protein serine/threonin kinase domain of 302 amino acids at its N-terminus. At the C-terminus, there is a 7 amino acid long region that is required for Cvt trafficking.
Omegasomes act as progenitors of autophagosome formation during the autophagy pathway. [14] There are various autophagosome mediators involved in autophagy, however it is the omegasome regulation of the pathway that provides a smooth transition of autophagosome formation, and enrichment of nutrients in the cells.
