Function

E1-like activating enzyme involved in the 2 ubiquitin-like systems required for cytoplasm to vacuole transport (Cvt) and autophagy. Activates ATG12 for its conjugation with ATG5 as well as the ATG8 family proteins for their conjugation with phosphatidylethanolamine. Both systems are needed for the ATG8 association to Cvt vesicles and autophagosomes membranes. Required for autophagic death induced by caspase-8 inhibition. Facilitates LC3-I lipidation with phosphatidylethanolamine to form LC3-II which is found on autophagosomal membranes (PubMed:34161705). Required for mitophagy which contributes to regulate mitochondrial quantity and quality by eliminating the mitochondria to a basal level to fulfill cellular energy requirements and preventing excess ROS production. Modulates p53/TP53 activity to regulate cell cycle and survival during metabolic stress. Also plays a key role in the maintenance of axonal homeostasis, the prevention of axonal degeneration, the maintenance of hematopoietic stem cells, the formation of Paneth cell granules, as well as in adipose differentiation. Plays a role in regulating the liver clock and glucose metabolism by mediating the autophagic degradation of CRY1 (clock repressor) in a time-dependent manner (By similarity).

Notes

We have had 1 attempt at IHC-P with ab133528 in our own lab. We observed both cytoplasmic and nuclear staining on several tissues (including human stomach, kidney and pancreatic cancer), under our experimental conditions. For IHC-P on human tissues, we would recommend using Anti-ATG7 antibody [EP1759Y] ab52472.

Activity summary

ATG7 also known as Autophagy Related 7 is an essential protein involved in the autophagy process. It functions as an E1-like enzyme activating and transferring ubiquitin-like proteins such as ATG12 and LC3. The molecular weight of ATG7 is approximately 78 kDa. It is widely expressed in various tissues although expression levels can differ. One can detect ATG7 using immunoassays like ELISA or antibodies specifically targeting ATG7. Understanding its mechanical role is key to studying cellular homeostasis.

Biological function summary

ATG7 plays a significant role in autophagy a cellular degradation pathway critical for cell survival under stress. ATG7 contributes to the formation of autophagosomes by facilitating conjugation of ATG8 family proteins including LC3 to phosphatidylethanolamine. It acts within complexes that regulate cellular energy balance and stress responses ensuring cells maintain their function and integrity. Knockdown of ATG7 can impair autophagic flux highlighting its importance in maintaining cellular processes.

Pathways

ATG7 is a central player in the autophagy pathway influencing cellular metabolism and turnover. It interacts closely with ATG5 and ATG12 in this pathway to form a conjugation system essential for autophagosome elongation. Additionally ATG7 is involved in the mTOR signaling pathway which regulates nutrient sensing and cellular growth. Interaction with proteins like mTOR allows ATG7 to integrate signals from nutrient availability and stress responses finely tuning the autophagy process.

Associated diseases and disorders

ATG7 dysfunction has connections to cancer and neurodegenerative diseases like Alzheimer's. Abnormal ATG7 activity disrupts autophagic balance possibly leading to the accumulation of damaged proteins and organelles contributing to disease progression. In cancer altered ATG7 expression may influence tumor survival by affecting cellular stress responses. Proteins such as p53 involved in cell cycle regulation often show association with ATG7-related pathways indicating a complex network influencing disease states. Understanding ATG7's role in these conditions can help explore potential therapeutic strategies.

    False colour image of Western blot: Anti-ATG7 antibody [EPR6251] staining at 1/10000 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (Anti-GAPDH antibody [6C5] - Loading Control ab8245) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab133528 was shown to bind specifically to ATG7. A band was observed at 75 kDa in wild-type HeLa cell lysates with no signal observed at this size in ATG7 knockout cell line Human ATG7 knockout HeLa cell line ab283307 (knockout cell lysate Human ATG7 knockout HeLa cell lysate ab287353). To generate this image, wild-type and ATG7 knockout HeLa cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776) at 1/20000 dilution.
