Plays an essential role in autophagy. Homooligomer. Interacts with ATG5. Part of either the minor and major complexes respectively composed of 4 sets of ATG12-ATG5 and ATG16L1 (400 kDa) or 8 sets of ATG12-ATG5 and ATG16L1 (800 kDa). Belongs to the WD repeat ATG16 family. 5 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
Protein type: Adaptor/scaffold; Membrane protein, peripheral; Autophagy
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.
