Verification Images

  • Experimental Validation Results for ATG3 Antibody (YA5928)
    Western blot analysis of extracts from K562 (lane 2, 20ug), Hela (lane3, 20μg) and Jurkat (lane4, 20μg) using ATG3 Antibody (HY-P86236). Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80993, 1/10,000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Rabbit IgG-HRP Secondary Antibody (HY-P8001,1/10,000) was used for 1 hour at room temperature.

Background

  • Function

    ATG3 is an 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. 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. 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. Interacts with negatively-charged membranes promoting membrane tethering and enhancing LC3/GABARAP lipidation. 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. ATG12-ATG3 conjugation promotes late endosome to lysosome trafficking and basal autophagosome maturation via its interaction with PDCD6IP. 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. Promotes primary ciliogenesis by removing OFD1 from centriolar satellites via the autophagic pathway[1][2][3][4][5][6][7][8][9].

  • Isoforms & Post-Translational Modification

    Q9NT62 has 2 isomers: Q9NT62-1: 35864 Da (predicted); Q9NT62-2: 35467 Da (predicted).
    Cleaved by CASP8 upon death ligand binding such as tumor necrosis factor-alpha (PubMed:22644571). CASP8 cleavage blocks survival-related autophagy and favors apoptosis (PubMed:22644571);Conjugated to ATG12 at Lys-243. ATG12-conjugation plays a role in regulation of mitochondrial homeostasis and cell death, while it is not involved in phosphatidylethanolamine-conjugation to ATG8-like proteins and autophagy

  • Subunit

    Homdimer (PubMed:24191030). Interacts with ATG7; this interaction forms an E1-E2 complex that is essential for the transfer of GABARAP thioester from ATG7 to ATG3 and disrupts interaction with the E3 enzyme complex (PubMed:11825910, PubMed:22170151, PubMed:24186333, PubMed:26043688, PubMed:37252361). Interacts with ATG12; this interaction is ATG7-dependent, essential for phosphatidylethanolamine (PE)-conjugated ATG8-like proteins formation and also mediates the autoconjugation of ATG12 on ATG3 (PubMed:11825910, PubMed:12207896, PubMed:22170151, PubMed:24191030). Interacts with FNBP1L (PubMed:19342671). Interacts with the E3 enzyme complex composed of 4 sets of ATG12-ATG5 and ATG16L1 (400 kDa); this interaction disrupts interaction with ATG7 and promotes ATG8-like proteins lipidation (PubMed:24186333, PubMed:24191030, PubMed:37252361). Interacts with GABARAP and MAP1LC3A (PubMed:37252361). Interacts with the ATG12-ATG5 conjugate; this interaction inhibits ATG8-like proteins lipidation (PubMed:12207896). Interacts (ATG12-ATG3 conjugate form) with PDCD6IP (via the BRO1 domain); this interaction is bridged by ATG12 and promotes multiple PDCD6IP-mediated functions such as endolysosomal trafficking, macroautophagy and exosome biogenesis (By similarity)
