HVEM (TNFRSF14) directly binds HSV glycoprotein D (gD) in a specific physical interaction demonstrated by biosensor and gel filtration chromatography, forming a 1:1 molar ratio complex with apparent mass of ~113 kDa; this interaction mediates HSV entry into HVEM-expressing cells and is dependent on native gD conformation but not N-linked glycosylation. |

Structure-based alanine-scanning mutagenesis of HveA identifies a binding hot spot centered on HveA-Y23, which protrudes into a crevice on gD; an intermolecular β-sheet between gD and HveA residues 35–37 contributes to binding, and the C37–C19 disulfide bond in CRD1 is critical for gD binding. CRD2 provides structural support rather than direct contact energy. |
