Genes affected

RFTN1 (HGNC:30278): (raftlin, lipid raft linker 1) Enables double-stranded RNA binding activity. Involved in B cell receptor signaling pathway; membrane raft assembly; and positive regulation of growth rate. Acts upstream of or within dsRNA transport; response to exogenous dsRNA; and toll-like receptor 3 signaling pathway. Located in endosome; membrane raft; and plasma membrane. Part of protein-containing complex. [provided by Alliance of Genome Resources, Apr 2022]
