CC   -!- FUNCTION: Component of the signaling pathway of IL-1 and Toll-like
CC       receptors. Inhibits cell activation by microbial products. Connects the
CC       ubiquitin pathway to autophagy by functioning as a ubiquitin-ATG8
CC       family adapter and thus mediating autophagic clearance of ubiquitin
CC       conjugates. The TOLLIP-dependent selective autophagy pathway plays an
CC       important role in clearance.
CC   -!- SUBUNIT: Interacts with ATG8 family proteins (via AIM motifs), and
CC       ubiquitin (via CUE domain). of cytotoxic polyQ proteins aggregates.
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- DOMAIN: Both ATG8-interaction motifs (AIM1 and AIM2) are required for
CC       the association with ATG8 family proteins. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the tollip family. {ECO:0000305}.
