CC -!- FUNCTION: Attaches the virion to the host cell membrane by interacting
CC with heparan sulfate, initiating the infection. Interacts with host
CC CX3CR1, the receptor for the CX3C chemokine fractalkine, to modulate
CC the immune response and facilitate infection. Unlike the other
CC paramyxovirus attachment proteins, lacks both neuraminidase and
CC hemagglutinating activities (By similarity). {ECO:0000250}.
CC -!- FUNCTION: Secreted glycoprotein G helps RSV escape antibody-dependent
CC restriction of replication by acting as an antigen decoy and by
CC modulating the activity of leukocytes bearing Fcgamma receptors.
CC {ECO:0000250}.
CC -!- SUBUNIT: Homooligomer. Interacts (via N-terminus) with protein M.
CC Interacts with protein F; this interaction occurs on the surface of
CC infected cells. Interacts with protein SH. Interacts with host CX3CR1;
CC this interaction modulates host immune response (By similarity).
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Virion membrane. Host cell surface {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: [Isoform Secreted glycoprotein G]: Secreted.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative initiation; Named isoforms=2;
CC Name=Membrane-bound glycoprotein G;
CC IsoId=Q86695-1; Sequence=Displayed;
CC Name=Secreted glycoprotein G;
CC IsoId=Q86695-2; Sequence=VSP_036521;
CC -!- DOMAIN: Contains a linear heparin binding domain essential for virus
CC attachment to the host.
CC -!- PTM: May carry a lot of separate O-linked carbohydrate chains
CC distributed among serine and threonine residues. {ECO:0000250}.
CC -!- PTM: Palmitoylated. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the pneumoviruses glycoprotein G family.
CC {ECO:0000305}.
