HVEM (herpes virus entry mediator, TNFRSF14, CD270) is a member of the tumor necrosis factor receptor superfamily (TNFRSF) . HVEM is a bidirectional molecular switch that transduces positive and negative signals. HVEM can deliver proinflammatory and survival signals when engaged by BTLA or LIGHT, stimulating lymphocyte proliferation, activation, and inducing inflammatory reactions. While, HVEM binds to CD160 and BTLA, inhibiting T- and B-lymphocyte activation and proliferation[2][3]. HVEM/TNFRSF14 Protein, Human (HEK293, His) is a recombinant protein with a C-Terminal His label, It is produced in HEK293 cells.
