Name Betaherpesvirus glycoprotein L (gL) domain
Function Two glycoprotein complexes are conserved throughout the three herpesvirus subfamilies: the trimeric glycoprotein B (gB) that functions as a membrane fusogen and the heterodimeric glycoprotein H/glycoprotein L (gH/gL), the role of which is less clearly defined. The intrinsic structural plasticity of gH/gL enables it to function as a signal integration machine that can accept diverse regulatory inputs and convert them into a "trigger" signal that activates the fusogenic ability of gB.
Scope(s) Viruses
Betaherpesvirinae
Example(s) O92277 (GL_GPCMV);

Comments [?]

SUBCELLULAR LOCATIONVirion membrane; Peripheral membrane protein; Extracellular side. Host cell membrane; Peripheral membrane protein; Extracellular side. Host Golgi apparatus, host trans-Golgi network. Note=gL associates with the extravirion surface through its binding to gH. During virion morphogenesis, this protein probably accumulates in the host trans-Golgi where secondary envelopment occurs.
SIMILARITYBelongs to the herpesviridae glycoprotein L (gL) family. Betaherpesvirinae gL subfamily.
