Predicted to enable double-stranded RNA binding activity. Predicted to be involved in several processes, including T cell antigen processing and presentation; antigen receptor-mediated signaling pathway; and positive regulation of growth rate. Predicted to act upstream of or within dsRNA transport; response to exogenous dsRNA; and toll-like receptor 3 signaling pathway. Predicted to be located in endosome; membrane raft; and plasma membrane. Predicted to be part of protein-containing complex. Orthologous to human RFTN1 (raftlin, lipid raft linker 1).
