This gene encodes a member of the TNF (tumor necrosis factor) receptor superfamily. The encoded protein functions in signal transduction pathways that activate inflammatory and inhibitory T-cell immune response. It binds herpes simplex virus (HSV) viral envelope glycoprotein D (gD), mediating its entry into cells. Alternative splicing results in multiple transcript variants.,TNFRSF14,ATAR,CD270,HVEA,HVEM,LIGHTR,TR2,Cancer,Signal Transduction,Cell Biology & Developmental Biology,Apoptosis,Growth factor,TNF,Immunology & Inflammation,CD markers,Cytokines,TNF,NF-kB Signaling Pathway,Cell Intrinsic Innate Immunity Signaling Pathway,TNFRSF14
