DESCRIPTION

Also known as CACO2_HUMAN, CALCOCO2, NDP52. Xenophagy-specific receptor required for autophagy-mediated intracellular bacteria degradation. Acts as an effector protein of galectin-sensed membrane damage that restricts the proliferation of infecting pathogens such as Salmonella typhimurium upon entry into the cytosol by targeting LGALS8-associated bacteria for autophagy (PubMed:22246324). Initially orchestrates bacteria targeting to autophagosomes and subsequently ensures pathogen degradation by regulating pathogen-containing autophagosome maturation (PubMed:23022382, PubMed:25771791). Bacteria targeting to autophagosomes relies on its interaction with MAP1LC3A, MAP1LC3B and/or GABARAPL2, whereas regulation of pathogen-containing autophagosome maturation requires the interaction with MAP3LC3C (PubMed:23022382, PubMed:25771791). May play a role in ruffle formation and actin cytoskeleton organization and seems to negatively regulate constitutive secretion (PubMed:17635994). Dimer (PubMed:23511477). Part of a complex consisting of CALCOCO2, TAX1BP1 and MYO6 (PubMed:17635994). Interacts with GEMIN4 (PubMed:12869526). Interacts with ATG8 family members MAP1LC3A, MAP1LC3B, GABARAP, GABARAPL1 and GABARAPL2 (PubMed:25771791). Interacts with ATG8 family member MAP1LC3C (PubMed:23022382). Interacts with LGALS8 (PubMed:22246324, PubMed:25771791, PubMed:23511477, PubMed:23386746).
