CC -!- FUNCTION: Major attachment protein that mediates binding of the virus
CC to cell surface heparan sulfate or chondroitin sulfate. Also plays
CC several roles in host immune evasion by inhibiting the host complement
CC cascade activation, and by providing a shield against neutralizing
CC antibodies that interfere with gB-gD, gB-gH/gL or gD-gH/gL interactions
CC (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Interacts with host complement component C3b; this interaction
CC inhibits host immune response by disregulating complement cascade.
CC {ECO:0000269|PubMed:2849025}.
CC -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000305}; Single-pass
CC membrane protein {ECO:0000305}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing, Alternative initiation; Named isoforms=2;
CC Name=gC;
CC IsoId=P10228-1; Sequence=Displayed;
CC Name=gCsec;
CC IsoId=P10228-2; Sequence=VSP_040892;
CC -!- MISCELLANEOUS: There are seven external glycoproteins in HSV-1 and 2:
CC gH, gB, gC, gG, gD, gI, and gE.
CC -!- MISCELLANEOUS: [Isoform gC]: Membrane-bound gC.
CC -!- MISCELLANEOUS: [Isoform gCsec]: Secreted. {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the herpesviridae glycoprotein C family.
CC {ECO:0000305}.
