FEATURES

DESCRIPTION

Also known as RFIP3_HUMAN, RAB11FIP3, ARFO1, KIAA0665. Acts as a regulator of endocytic traffic by participating in membrane delivery. Required for the abcission step in cytokinesis, possibly by acting as an 'address tag' delivering recycling endosome membranes to the cleavage furrow during late cytokinesis. Also required for the structural integrity of the endosomal recycling compartment during interphase. May play a role in breast cancer cell motility by regulating actin cytoskeleton. Acts as an adapter protein linking the dynein motor complex to various cargos and converts dynein from a non-processive to a highly processive motor in the presence of dynactin. Facilitates the interaction between dynein and dynactin and activates dynein processivity (the ability to move along a microtubule for a long distance without falling off the track) (PubMed:25035494). Homodimer. Forms a complex with Rab11 (RAB11A or RAB11B) and ARF6. Interacts with RAB11A; the interaction is direct. Interacts with RAB11B, RAB25 and RAB11FIP4. Interacts with ARF6; according to PubMed:16148947, it specifically interacts with ARF6 but not ARF5. Interacts with ARF6; according to PubMed:17030804 but not PubMed:16148947. Interacts with RACGAP1/MgcRacGAP; interaction takes place during late stage of cytokinesis and is required for recruitment to the midbody. Interacts with ASAP1 and EXOC7. Interacts with dynein intermediate chain and dynactin (DCTN1) (PubMed:25035494).
