The lysosome's hydrolases degrade the autophagosome-delivered contents and its inner membrane. [3] 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.
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 ...
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]
Atg8 is a monomer of 117 aminoacids and a molecular weight of 13,6kDa. It consists of a 5-stranded β-sheet, which is enclosed by two α-helices at one side and one α-helix at the other side and exhibits a conserved GABARAP domain. [2]
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.
Autophagy-related protein 13 also known as ATG13 is a protein that in humans is encoded by the KIAA0652 gene. [5]ATG13 is an autophagy factor required for phagosome formation. . ATG13 is a target of the TOR kinase signaling pathway that regulates autophagy through phosphorylation of ATG13 and ULK1, and the regulation of the ATG13-ULK1-RB1CC1 comp
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.
RNA expression of VPS35 is ubiquitous throughout the body, but are higher in the brain, heart, gonads, spleen, and skeletal muscle, and lower in the lung, liver, kidney, and blood leukocytes. [15] [16] Crystal structure of the cargo recognition complex. VPS26 (yellow), VPS35 (light blue), and VPS29 (light purple) form a trimer.
