This antibody is designed, produced, and validated as part of a collaboration between Rockland and the National Cancer Institute (NCI). Rab11 Family-Interacting Protein 3 (FIP3)/Arfophilin-1 and FIP4/Arfophilin-2 are dual effectors for Rab11 and the ADP-ribosylation factor Arf6. Rab11 and Arf6 are involved in membrane delivery from recycling endosomes to the plasma membrane during cytokinesis. The dual Rab11/Arf6 binding proteins, FIP3 and FIP4, function in the delivery of recycling endosomes to the cleavage furrow and are, together with Rab11, essential for completion of abscission, the terminal step of cytokinesis. An interaction between Rab11-FIP3 and ASAP1 has also been identified. ASAP1 is an Arf GTPase-activating protein that has been implicated in the invasive properties of uveal melanoma and mammary carcinoma. Therefore, may play a role in breast cancer cell motility by regulating actin cytoskeleton. Also, 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). Anti-Rab11 Antibody is useful for researchers interested in organelle transport, endocytosis, and cancer research.

Application Note

This affinity purified antibody has been tested for use in ELISA and western blotting.  Specific conditions for reactivity should be optimized by the end user.  Although the predicted molecular weight of FIP3 is 82.4 kDa, a band corresponding to FIP3 was observed at 120 kDa in human cell lysates and at 150 kDa in mouse cell lysates.  The identity of a 40 kDa band, observed in western blotting against both HeLa and 293T cell lysates, is unknown (personal communication, P. Randazzo, CCR-NCI, Bethesda, MD).


This affinity purified antibody is directed against human FIP3 protein. The product was affinity purified from monospecific antiserum by immunoaffinity chromatography.  A BLAST analysis was used to suggest cross-reactivity with Rab11 protein from mouse based on approximately 92% protein:protein homology over the region of the immunizing sequence.  Reactivity against homologues from other sources is not known.
