UniProt functional annotation for P57083

UniProt code: P57083.

Organism: Human herpesvirus 1 (strain Patton) (HHV-1) (Human herpes simplex virus 1).
Taxonomy: Viruses; Duplodnaviria; Heunggongvirae; Peploviricota; Herviviricetes; Herpesvirales; Herpesviridae; Alphaherpesvirinae; Simplexvirus.
 
Function: Envelope glycoprotein that binds to the potential host cell entry receptors TNFRSF14/HVEM, NECTIN1 and 3-O-sulfated heparan sulfate. May trigger fusion with host membrane, by recruiting the fusion machinery composed of gB and gH/gL (By similarity). {ECO:0000250}.
 
Subunit: Homodimer (By similarity). Interacts with host receptor TNFRSF14. Interacts with host receptor NECTIN1. Interacts (via profusion domain) with gB; this interaction occurs in the absence of gH/gL. Interacts (via profusion domain) with gH/gL heterodimer; this interaction occurs in the absence of gB. Associates with the gB-gH/gL- gD complex. Interacts (via C-terminus) with UL11 tegument protein. Interacts with host RSAD2 (By similarity). {ECO:0000250}.
Subcellular location: Virion membrane {ECO:0000250}; Single-pass type I membrane protein {ECO:0000250}. Host Golgi apparatus {ECO:0000250|UniProtKB:Q69091}. Note=During virion morphogenesis, this protein probably accumulates in the endosomes and trans-Golgi where secondary envelopment occurs. {ECO:0000250}.
Similarity: Belongs to the herpesviridae glycoprotein D family. {ECO:0000305}.
