General description

ATG3 is a member of the autophagy-related protein family and is involved in the formation of the autophagosome.
Autophagy-related protein 3 (ATG3) is a member of the autophagy-related protein family. It is a mammalian homolog of yeast Apg3p/ Atg3 is ubiquitously expressed in human tissues.

Immunogen

synthetic peptide corresponding to amino acids 17-32 of human Atg3, conjugated to KLH via a C-terminal cysteine residue. The corresponding sequence is identical in rat and mouse.

Application

Anti-ATG3 antibody produced in rabbit has been used in western blotting and immunoprecipitation.

Biochem/physiol Actions

Autophagy-related protein 3 (ATG3) is involved in the formation of the autophagosome. the mammalian homolog of yeast Apg3p/Aut1p, is an E2-like enzyme that catalyzes the conjugation reaction between Atg8 and phosphatidylethanolamine (PE). Golgi-associated ATPase enhancer of 16 kDa (GATE-16), GABAA receptor-associated protein (GABARAP), and microtubule-associated protein light chain 3 (MAP-LC3) are substrates for Atg3. MAP-LC3 is the preferred substrate. Atg3 interacts with Atg7 to form an E1-E2 complex, and with Atg12, which is a substrate for Atg7 but not for Atg3. Moreover, overexpression of Atg3 facilitates the formation of the Atg12-Atg5 conjugate.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

The ubiquitin-like molecule ATG12 is required for the early steps of autophagy. Recently, we identified ATG3, the E2-like enzyme required for LC3 lipidation during autophagy, as an ATG12 conjugation target. Here, we demonstrate that cells lacking ATG12-ATG3 have impaired basal
