CC   -!- FUNCTION: Involved in endocytic trafficking by stabilizing organelles
CC       of the endocytic pathway. Probably acts as a cytoskeletal linker
CC       protein required to tether endosome vesicles to the cytoskeleton.
CC       Involved in modulation of endocytosis at stages required for down-
CC       regulation of membrane proteins that control synapse size. Not involved
CC       in synaptic vesicle recycling. Required in R7 cells for boss
CC       endocytosis into multivesicular bodies (MVBs). Has a role in regulating
CC       adult longevity. {ECO:0000250|UniProtKB:Q24185}.
CC   -!- SUBUNIT: Homodimer. Interacts with microtubules via its N-terminus.
CC       {ECO:0000250|UniProtKB:Q24185}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton
CC       {ECO:0000250|UniProtKB:Q24185}. Endosome
CC       {ECO:0000250|UniProtKB:Q24185}. Synapse {ECO:0000250|UniProtKB:Q24185}.
CC       Note=Enriched at neuromuscular synapses, in both presynaptic and
CC       postsynaptic regions. {ECO:0000250|UniProtKB:Q24185}.
CC   -!- DOMAIN: The coiled coil domain mediates homodimerization.
CC       {ECO:0000250|UniProtKB:Q24185}.
CC   -!- SIMILARITY: Belongs to the hook family. {ECO:0000305}.
