The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptor has been shown to activate NF-kappaB through its interaction with adaptor proteins TRAF2 and TRAF5. Knockout studies in mice suggested that this receptor promotes the expression of apoptosis inhibitors BCL2 and BCL2lL1/BCL2-XL, and thus suppresses apoptosis. The knockout studies also suggested the roles of this receptor in CD4+ T cell response, as well as in T cell-dependent B cell proliferation and differentiation.,TNFRSF4,ACT35,CD134,IMD16,OX40,TXGP1L,Immunology & Inflammation,CD markers,Cytokines,TNF,NF-kB Signaling Pathway,Cell Intrinsic Innate Immunity Signaling Pathway,Stem Cells,Hematopoietic Progenitors,TNFRSF4
