Binds phospholipid vesicles containing phosphatidylinositol 3-phosphate and participates in endosomal trafficking. Homodimer. Binds STX6. Binds RAB5A, RAB5B, RAB5C and RAB22A that have been activated by GTP-binding. Interacts with ERBB2. Note: This description may include information from UniProtKB.
