Required for autophagy. Conjugates to ATG12 and associates with isolation membrane to form cup-shaped isolation membrane and autophagosome. The conjugate detaches from the membrane immediately before or after autophagosome formation is completed. The ATG5-ATG12 conjugate forms a complex with several units of ATG16. Interacts with TECPR1; the interaction is direct and does not take place when ATG16 is associated with the ATG5- ATG12 conjugate. By apoptotic stimuli. Ubiquitous. The mRNA is present at similar levels in viable and apoptotic cells, whereas the protein is dramatically highly expressed in apoptotic cells. Belongs to the ATG5 family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
Protein type: Apoptosis; Autophagy; Ubiquitin conjugating system

Biological Process: response to drug; response to fungus; apoptosis; ventricular cardiac muscle cell development; C-terminal protein lipidation; post-translational protein modification; vasodilation; regulation of release of sequestered calcium ion into cytosol; cellular response to nitrogen starvation; heart contraction; regulation of cytokine secretion during immune response; mitochondrion degradation; autophagy; innate immune response; negative regulation of protein ubiquitination; blood vessel remodeling; negative regulation of interferon type I production; otolith development; negative regulation of apoptosis; autophagic vacuole formation
SS: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
