ATG7 Antibody – Rabbit Polyclonal

This gene was identified based on homology to Pichia pastoris GSA7 and Saccharomyces cerevisiae APG7. In the yeast, the protein appears to be required for fusion of peroxisomal and vacuolar membranes. The protein shows homology to the ATP-binding and catalytic sites of the E1 ubiquitin activating enzymes. [provided by RefSeq, Jan 2009]

ATG7: Functions as an E1 enzyme essential for multisubstrates such as ATG8-like proteins and ATG12. Forms intermediate conjugates with ATG8-like proteins (GABARAP, GABARAPL1, GABARAPL2 or MAP1LC3A). PE-conjugation to ATG8-like proteins is essential for autophagy. Also acts as an E1 enzyme for ATG12 conjugation to ATG5 and ATG3. Homodimer. Interacts with ATG3 and ATG12. The complex, composed of ATG3 and ATG7, plays a role in the conjugation of ATG12 to ATG5. Widely expressed, especially in kidney, liver, lymph nodes and bone marrow. Belongs to the ATG7 family. 2 isoforms of the human protein are produced by alternative splicing.
