Function
[GD_HHV11] Envelope glycoprotein that binds to the potential host cell entry receptors TNFRSF14/HVEM, PVRL1 and 3-O-sulfated heparan sulfate (By similarity). May trigger fusion with host membrane, by recruiting the fusion machinery composed of gB and gH/gL. [PVRL1_HUMAN] Promotes cell-cell contacts by forming homophilic or heterophilic trans-dimers. Heterophilic interactions have been detected between PVRL1/nectin-1 and PVRL3/nectin-3 and between PVRL1/nectin-1 and PVRL4/nectin-4. Functions as an entry receptor for herpes simplex virus and pseudorabies virus.[1]
Publication Abstract from PubMed
Multiple surface envelope proteins are involved in the human herpes simplex virus type 1 entry and fusion. Among them, glycoprotein D (gD) has an important role by binding to the host receptors such as herpes virus entry mediator and nectin-1. Although the complex structure of gD with herpes virus entry mediator has been established, the binding mode of gD with the nectin-1 is elusive. Nectin-1 is a member of the immunoglobulin (Ig)-like (three Ig-like domains) cell adhesion molecules and is believed to form a homodimer to exert its functions. Here we report the complex structure of gD and nectin-1 (three Ig domains), revealing that gD binds the first Ig domain of nectin-1 in a similar mode to the nectin-1 homodimer interaction. The key amino acids responsible for nectin-1 dimerization are also used for gD/nectin-1 binding. This result indicates that binding of gD to nectin-1 would preclude the nectin-1 dimerization, consequently abolishing its cell adhesion function.
