ATG7, also known as APG7, is a 78 kDa cytosolic ubiquitin-E1-like enzyme that plays a key role in the autophagic pathway of intracellular bulk degradation. It is required for the conjugation of ATG5 to ATG12, the lipidation of ATG8, and subsequent autophagosome formation. ATG7 is required for mitochondrial removal during erythropoiesis and for the maintenance of axonal homeostasis. Alternate splicing of human ATG7 generates an isoform that lacks 31 aa at the C-terminus, a region that is required for ATG8 lipidation. Human ATG7 shares 93% aa sequence identitiy with mouse and rat ATG7.
Post-translational: Acetylated by EP300.Polyubiquitinated on Lys-45 via 'Lys-63'-linked ubiquitin by TRIM32; this modification positiely regulates ATG8 and ATG12 activating enzyme activity leading to initiation of autophagy under metabolic stress.
21.5 kDa, under reducing conditions; 20.6 & 41.7 & 61.2 kDa, under non-reducing conditions.

Recombinant Human ATG7 Protein (rp218434) - SDS-PAGE 2 μg/lane of Recombinant Human ATG7 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing a band at 21.5 kDa under reducing conditions and 20.6 & 41.7 & 61.2 kDa under non-reducing conditions. ATG7 can form Homodimer. The three conformations under non-reducing conditions may correspond to distinct catalytic stages: adenylylation, substrate transfer, and thioester bond formation (Uniprot: O95352).
