RT "A role for adaptor protein-3 complex in the organization of the endocytic
RT pathway in Dictyostelium.";
RL Traffic 7:1528-1538(2006).
CC -!- FUNCTION: Part of the AP-3 complex, an adaptor-related complex which is
CC essential for the compartmentalization of the endocytic pathway.
CC {ECO:0000269|PubMed:17010123}.
CC -!- SUBUNIT: Adaptor protein complex 3 (AP-3) is a heterotetramer composed
CC of two large adaptins (delta-type subunit and beta-type subunit), a
CC medium adaptin (mu-type subunit) and a small adaptin (sigma-type
CC subunit). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Endosome membrane {ECO:0000250}.
CC -!- DEVELOPMENTAL STAGE: Constant expression throughout development.
CC {ECO:0000269|PubMed:11179674}.
CC -!- DISRUPTION PHENOTYPE: Cells are viable but are unable to retrieve
CC efficiently some proteins from early endocytic compartments.
CC {ECO:0000269|PubMed:17010123}.
CC -!- SIMILARITY: Belongs to the adaptor complexes medium subunit family.
CC {ECO:0000305}.
