Protein Structure

UniProt Annotation

Function

Plays a role in endocytosis and intracellular protein transport. Mediates trafficking of TF from early endosomes to recycling endosomes. Required for NGF-mediated endocytosis of NTRK1, and subsequent neurite outgrowth. Binds GTP and GDP and has low GTPase activity. Alternates between a GTP-bound active form and a GDP-bound inactive form. {ECO:0000269PubMed:16537905, ECO:0000269PubMed:21849477}.

Subcellular Localization

Endosome membrane {ECO:0000250}; Lipid- anchor {ECO:0000250}. Cell membrane {ECO:0000250}; Lipid-anchor {ECO:0000250}. Early endosome. Cell projection, ruffle. Cytoplasmic vesicle. Cytoplasmic vesicle, phagosome. Cytoplasmic vesicle, phagosome membrane {ECO:0000250}; Lipid-anchor {ECO:0000250}; Cytoplasmic side {ECO:0000250}. Note=Recruited to phagosomes containing S.aureus or M.tuberculosis.
