Rab11FIP1 Antibody recognizes endogenous levels of total Rab11FIP1 protein.
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Thr188 of human Rab11FIP1 protein. Antibodies are purified by protein A and peptide affinity chromatography.
Rab11 family proteins consist of closely related Rab11a, Rab11b, and Rab25. They are small GTPases thought to play an essential role in regulating endocytic membrane traffic (1,2). The GTP-bound active state Rab11 proteins interact with the Rab11 family interacting proteins (Rab11FIPs) via a conserved carboxy-terminal Rab11-binding domain (3,4). At least six members of the Rab11FIPs have been identified. Based on sequence homology and domain structures, Rab11FIP1, Rab11FIP2 and Rab11FIP5 are categorized as class I subfamily members, whereas Rab11FIP3 and Rab11FIP4 belong to the class II subfamily that bind Arf6 and Rab11 proteins (5-7). Research studies have implicated Rab11 family proteins and their interacting effectors in carcinogenesis (8,9).
