The ATG12 recombinant monoclonal antibody is produced using DNA recombinant technology and in vitro genetic manipulation. The process involves immunizing an animal with a synthesized peptide derived from human ATG12, isolating B cells, and selecting positive B cells. These selected B cells undergo screening and single clone identification. The genes encoding the light and heavy chains of the ATG12 antibody are amplified via PCR and inserted into a plasmid vector to create a recombinant vector. This vector is then transfected into a host cell line for antibody expression. The ATG12 recombinant monoclonal antibody is purified from the cell culture supernatant using affinity chromatography. It exhibits specificity for human ATG12 protein and finds application in ELISA.

The ATG12 protein is a key component of the autophagy pathway in cells. In the autophagy pathway, ATG12 forms a conjugate with ATG5 and ATG16L to form the ATG12-ATG5-ATG16L complex, which acts as an E3 ligase, catalyzing the lipidation of LC3. The lipidated form of LC3, called LC3-II, is recruited to the autophagosomal membrane, where it helps to form the autophagosome. The autophagosome then fuses with lysosomes, where the contents are degraded and recycled.

Target Background

Ubiquitin-like protein involved in autophagy vesicles formation. Conjugation with ATG5 through a ubiquitin-like conjugating system involving also ATG7 as an E1-like activating enzyme and ATG10 as an E2-like conjugating enzyme, is essential for its function. The ATG12-ATG5 conjugate acts as an E3-like enzyme which is required for lipidation of ATG8 family proteins and their association to the vesicle membranes.; (Microbial infection) May act as a proviral factor. In association with ATG5, negatively regulates the innate antiviral immune response by impairing the type I IFN production pathway upon vesicular stomatitis virus (VSV) infection. Required for the translation of incoming hepatitis C virus (HCV) RNA and, thereby, for the initiation of HCV replication, but not required once infection is established.

  1. miR-23a downregulation modulates the inflammatory response by targeting ATG12-mediated autophagy. PMID: 29845275
  2. the role of the autophagy elongation complex (ATG5-12/16L1) in Hepatitis C virus replication and membranous web formation, was examined. PMID: 28067309
  3. Ambra1 plays an important role in regulating the sensitivity of breast cancer cells to epirubicin. Regulatory effect of Ambra1 on epirubicin sensitivity is achieved through the regulation of autophagy by targeting ATG12. PMID: 30027574
  4. The finding that miR378 targets ATG12 indicated that miR378 may have a potential role in autophagy. These findings may provide novel insights into the mechanism of metastasis in cervical cancer and a novel therapeutic target for the treatment of cervical cancer. PMID: 29488616
  5. Results show that ATG12 is a downstream effector in MALAT1-mediated autophagy in gastric cancer cells. PMID: 29162158
  6. HBV gained access to Atg5-12/16L1 via interaction of its core protein with the Atg12 moiety of the complex. In contrast, subsequent autophagosome maturation and closure events were unnecessary for HBV replication, as evidenced by inhibition of Atg8/LC3 conjugation. Interfering with the HBV/Atg12 cross talk may be a tool for virus control. PMID: 29367244

  8. STAT3 and ATG12 are targets of miR-454-3p. PMID: 28182000
  9. above findings suggest that ATG5-ATG12 positively regulate anti-viral NF-kappaB and IRF3 signaling during FMDV infection, thereby limiting FMDV proliferation. FMDV has evolved mechanisms to counteract the antiviral function of ATG5-ATG12, via degradation of them by viral protein 3C(pro). PMID: 28102839

  17. study to identify role of conjugation between ATG12 and ATG5 in LC3 lipidation; structural and mutational analyses of ATG12~ATG5-ATG16N revealed the conjugation generates a patch across ATG12 and ATG5 required for E3 activity PMID: 23202584
  18. These data relate LC3B, ATG5 and ATG12 to mitochondrial quality control after oxidative damage, and to cellular longevity. PMID: 22170153
