Function

May function in transferrin receptor internalization at the plasma membrane through a cargo-specific control of clathrin- mediated endocytosis. Alternatively, may acts as a negative regulator of the amino acid-induced TOR signaling by inhibiting the formation of active Rag GTPase complexes. Preferentially binds inactive Rag GTPase complexes and prevents their interaction with the mTORC1 complex inhibiting its relocalization to lysosomes and its activation. Thereby, may indirectly regulate cell growth, proliferation and autophagy (By similarity). {ECO:0000250}.

Subcellular Localization

Membrane, clathrin-coated pit {ECO:0000250}. Cytoplasmic vesicle, clathrin-coated vesicle {ECO:0000250}. Nucleus {ECO:0000250}. Note=Specifically associated with transferrin receptor-containing clathrin-coated pits and clathrin- coated vesicles. May also localize to the nucleus (By similarity). {ECO:0000250}.
