Western blot - Anti-ATG3 antibody [EPR4801] - BSA and Azide free (AB226019)

This data was developed using the same antibody clone in a different buffer formulation (ab108251).

Lanes 1-4 : Merged signal (red and green). Green - ab108251 observed at 40 kDa. Red - loading control ab7291 observed at 50 kDa.

ab108251 Anti-ATG3 antibody [EPR4801] was shown to specifically react with ATG3 in wild-type HEK293T cells. Loss of signal was observed when knockout cell line ab266707 (knockout cell lysate ab257363) was used. Wild-type and ATG3 knockout samples were subjected to SDS-PAGE. ab108251 and Anti-alpha Tubulin antibody [DM1A] - Loading Control (ab7291) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Supplementary information

ATG3 also known as Autophagy-related protein 3 is an essential enzyme in the autophagy process. Its molecular weight is approximately 36 kDa. This protein facilitates the conjugation of LC3 (microtubule-associated protein 1A/1B-light chain 3) by acting as an E2-like enzyme. It is mainly expressed in tissues with high rates of autophagy including liver heart and brain.
Biological function summary

ATG3 plays an important role in the elongation of the autophagic membrane. It operates as a part of the autophagy machinery working closely with ATG7 an E1-like enzyme to transfer phosphatidylethanolamine (PE) to LC3 converting it into LC3-II. This lipidated form of LC3 is essential in the expansion and closure of the isolation membrane which forms the autophagosome the core structure for degradation and recycling of cellular components.

Pathways

ATG3 is a central player in the macroautophagy pathway a process critical for cellular homeostasis. It interacts with ATG7 to facilitate the lipidation of ATG8 family proteins which are important for autophagosome formation. Moreover ATG3 also links to apoptosis pathways where its balance with pro-apoptotic proteins helps regulate cell death processes.

ATG3 has been implicated in neurodegenerative diseases like Alzheimer's. This relates partly to its role in protein clearance which is essential for preventing toxic aggregations. Altered ATG3 function can lead to accumulation of misfolded proteins exacerbating disease. Moreover ATG3's interaction with proteins in the cancer-related pathways such as p53 shows its involvement in tumorigenesis through its influence on cell survival and death mechanisms.

Target data

E2 conjugating enzyme that catalyzes the covalent conjugation of the C-terminal Gly of ATG8-like proteins (GABARAP, GABARAPL1, GABARAPL2 or MAP1LC3A) to the amino group of phosphatidylethanolamine (PE)-containing lipids in the membrane resulting in membrane-bound ATG8-like proteins which is one of the key steps in the development of autophagic isolation membranes during autophagosome formation (PubMed : 24191030, PubMed : 33446636, PubMed : 37252361). Cycles back and forth between binding to ATG7 for loading with the ATG8-like proteins and binding to E3 enzyme, composed of ATG12, ATG5 and ATG16L1 to promote ATG8-like proteins lipidation (PubMed : 11825910, PubMed : 12207896, PubMed : 12890687, PubMed : 16704426, PubMed : 24186333). Also plays a role as a membrane curvature sensor that facilitates LC3/GABARAP lipidation by sensing local membrane stress associated with lipid-packing defects as occurs with high molar proportions of conical lipids or strident membrane curvature (By similarity). Interacts with negatively-charged membranes promoting membrane tethering and enhancing LC3/GABARAP lipidation (PubMed : 29142222). Also acts as an autocatalytic E2-like enzyme by catalyzing the conjugation of ATG12 to itself in an ATG7-dependent manner, this complex thus formed, plays a role in mitochondrial homeostasis but not in autophagy (By similarity). ATG12-ATG3 conjugation promotes late endosome to lysosome trafficking and basal autophagosome maturation via its interaction with PDCD6IP (By similarity). ATG12-ATG3 conjugate is also formed upon viccina virus infection, leading to the disruption the cellular autophagy which is not necessary for vaccinia survival and proliferation (By similarity). Promotes primary ciliogenesis by removing OFD1 from centriolar satellites via the autophagic pathway (By similarity).
