Summary
Autophagy involves Atg proteins forming the autophagosome. This review details the structure and function of Atg proteins, focusing on the Atg1 complex and conjugation systems.
Area of Science:
- Cellular Biology
- Molecular Biology
- Biochemistry
Background:
- Autophagy is a fundamental cellular process for degrading and recycling cellular components.
- The formation of the autophagosome is a critical step in autophagy.
- Autophagy-related (Atg) proteins orchestrate autophagosome biogenesis.
Purpose of the Study:
- To provide a structural-biological perspective on Atg proteins involved in autophagy.
- To elucidate the structure, interactions, and molecular roles of key Atg proteins.
- To focus on the Atg1 complex and Atg conjugation systems in yeast.
Main Methods:
- Literature review focusing on structural biology.
- Analysis of protein structures and interactions.
- Integration of data on molecular mechanisms.
Main Results:
- Detailed structural insights into Atg proteins, particularly the Atg1 complex.
- Explanation of how Atg proteins interact to facilitate autophagosome formation.
- Clarification of the roles of Atg conjugation systems in the process.
Conclusions:
- The Atg1 complex and conjugation systems are crucial for initiating autophagosome formation.
- Understanding the structural biology of Atg proteins is key to deciphering autophagy.
- This review consolidates structural and functional knowledge of Atg proteins in yeast autophagy.

01:27Autophagy
6.5K
Autophagy is a self-digesting process by which a cell protects itself from threats both within and outside the cell, ranging from abnormal proteins to invading bacteria. In this process, obsolete components of the cell and invading microbes are degraded by hydrolytic enzymes active in an acidic environment of the lysosomal lumen.
An autophagic pathway consists of a series of signaling events activated in response to diverse stress and physiological conditions such as food deprivation,...

01:36Delivery Pathways to the Lysosome
10.6K
Eukaryotic cells use different mechanisms to eliminate toxic waste obsolete and worn-out substances. Lysosomes play a pivotal role in this, and hence, these substances are carried to the lysosome from other parts of the cell and extracellular space through different pathways. The most elaborately studied pathways to the lysosome are the endocytic pathways.

01:18Autophagic Cell Death
5.1K
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.

01:17Phagocytosis of Apoptotic Cells
5.7K
Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or immature dendritic cells. Non-professional phagocytes such as epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes.

01:30Overview of Cell Death
11.3K
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

53.2K
Autocrine signaling is one of the many signaling mechanisms that function inside multicellular organisms to carry out intercellular communication. In this type of signaling mechanism, the same cell that secretes an extracellular signaling molecule also expresses the receptors to bind and respond to that signaling molecule.
