Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Plays an essential role in autophagy By similarity.
Subunit structure	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) By similarity.
Subcellular location	CytoplasmBy similarity. Preautophagosomal structure membrane; Peripheral membrane proteinBy similarity. Note= Localized to preautophagosomal structure (PAS) where it is involved in the membrane targeting of ATG5 By similarity.
Involvement in disease	Genetic variations in ATG16L1 are associated with susceptibility to inflammatory bowel disease type 10 (IBD10) [MIM:611081]. IBD is characterized by a chronic relapsing intestinal inflammation. IBD is subdivided into Crohn disease (CD) and ulcerative colitis phenotypes. IBD10 individuals show the phenotype characteristic to CD. It may involve any part of the gastrointestinal tract, but most frequently the terminal ileum and colon. CD is commonly classified as autoimmune disease.
Sequence similarities	Belongs to the WD repeat ATG16 family. Contains 7 WD repeats.
Sequence caution	The sequence BAB15448.1 differs from that shown. Reason: Erroneous translation. Wrong choice of CDS.
