Invitrogen™ Human RAB11FIP1 (aa 423-508) Control Fragment Recombinant Protein

Description

Highest antigen sequence indentity to the following orthologs: Mouse (55%), Rat (55%). This recombinant protein control fragment may be used for blocking experiments with the corresponding antibody, PA5-55276 (PA5-55276. In IHC/ICC and WB experiments, we recommend a 100x molar excess of the protein fragment control based on the concentration and the molecular weight. Pre-incubate the antibody-protein control fragment mixture for 30 min at room temperature.

Rab11-FIP1 (Rab 11 family-interacting protein 1), also known as Rab-coupling protein (RCP), is a 1283 amino acid Rab 11 effector protein. Rab11-FIP1, by interacting with Rab GTPases, is involved in the endosomal recycling process and may play a role in controlling membrane trafficking along the phagocytic pathway and during phagocytosis. Localized to the recycling endosome, the cytoplasmic membrane and phagosome membranes, Rab11-FIP1 is expressed as five isoforms produced by alternative splicing. As the most highly expressed isoform, isoform two of Rab11-FIP1 is expressed in brain, lung, testis, small intestine, spleen and heart. Isoform two of Rab11-FIP1 also has been found to form a homooligomer and is believed to interact with many Rab GTPases, including Rab 4A, Rab 11A, Rab 11B and Rab 25.
