CC -!- FUNCTION: Xenophagy-specific receptor required for autophagy-mediated
CC intracellular bacteria degradation (By similarity). Acts as an effector
CC protein of galectin-sensed membrane damage that restricts the
CC proliferation of infecting pathogens upon entry into the cytosol by
CC targeting LGALS8-associated bacteria for autophagy (By similarity).
CC Initially orchestrates bacteria targeting to autophagosomes and
CC subsequently ensures pathogen degradation by regulating pathogen-
CC containing autophagosome maturation (By similarity). Bacteria targeting
CC to autophagosomes relies on its interaction with MAP1LC3A, MAP1LC3B
CC and/or GABARAPL2, whereas regulation of pathogen-containing
CC autophagosome maturation requires the interaction with MAP3LC3C (By
CC similarity). May play a role in ruffle formation and actin cytoskeleton
CC organization and seems to negatively regulate constitutive secretion
CC (By similarity). {ECO:0000250|UniProtKB:Q13137}.
CC -!- SUBUNIT: Dimer. Part of a complex consisting of CALCOCO2, TAX1BP1 and
CC MYO6. Interacts with GEMIN4. Interacts with ATG8 family members
CC MAP1LC3A, MAP1LC3B, GABARAP, GABARAPL1 and GABARAPL2. Interacts with
CC ATG8 family member MAP1LC3C. Interacts with LGALS8.
CC {ECO:0000250|UniProtKB:Q13137}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, perinuclear region
CC {ECO:0000250|UniProtKB:Q13137}. Cytoplasm, cytoskeleton
CC {ECO:0000250|UniProtKB:Q13137}. Cytoplasmic vesicle, autophagosome
CC membrane {ECO:0000250|UniProtKB:Q13137}; Peripheral membrane protein
CC {ECO:0000305}.
CC -!- DOMAIN: The MYO6-binding domain is required for autophagy-mediated
CC degradation of infecting bacteria such as Salmonella typhimurium, but
CC not for bacteria targeting to autophagosomes.
CC {ECO:0000250|UniProtKB:Q13137}.
CC -!- DOMAIN: The LGALS8-binding domain is essential for the recruitment to
CC cytosol-exposed infecting bacteria. {ECO:0000250|UniProtKB:Q13137}.
CC -!- DOMAIN: The CLIR (LC3C-interacting region) motif is required for
CC interaction with MAP1LC3C, but dispensable for CALCOCO2-mediated
CC autophagosome maturation. {ECO:0000250|UniProtKB:Q13137}.
CC -!- DOMAIN: The LIR-like motif is required for interaction with MAP1LC3A,
CC MAP1LC3B and GABARAPL2, as well as for CALCOCO2-mediated autophagosome
CC maturation. {ECO:0000250|UniProtKB:Q13137}.
CC -!- SIMILARITY: Belongs to the CALCOCO family. {ECO:0000305}.
