RFTN1

RFTN1 (Raftlin, Lipid Raft Linker 1) is a Protein Coding gene. Gene Ontology (GO) annotations related to this gene include double-stranded RNA binding. An important paralog of this gene is RFTN2.

Raftlin, Lipid Raft Linker 1

Involved in protein trafficking via association with clathrin and AP2 complex (PubMed:27022195, PubMed:21266579).
Upon bacterial lipopolysaccharide stimulation, mediates internalization of TLR4 to endosomes in dendritic cells and macrophages; and internalization of poly(I:C) to TLR3-positive endosomes in myeloid dendritic cells and epithelial cells; resulting in activation of TICAM1-mediated signaling and subsequent IFNB1 production (PubMed:27022195, PubMed:21266579).
Involved in T-cell antigen receptor-mediated signaling by regulating tyrosine kinase LCK localization, T-cell dependent antibody production and cytokine secretion (By similarity).
May regulate B-cell antigen receptor-mediated signaling (PubMed:12805216).
May play a pivotal role in the formation and/or maintenance of lipid rafts (PubMed:12805216).

Translocates from cytoplasm to cell membrane where it colocalizes with poly (I:C) and then moves to endosomes where it colocalizes with TLR3 (PubMed:21266579).
Translocates from cytoplasm to cell membrane where it colocalizes with TLR4 and then together with TLR4 moves to endosomes, upon lipopolysaccharide stimulation (PubMed:27022195).
