CC -!- FUNCTION: [Isoform Membrane-bound glycoprotein G]: Attaches the virion
CC to the host cell membrane by interacting with heparan sulfate,
CC initiating the infection. Interacts with host CX3CR1, the receptor for
CC the CX3C chemokine fractalkine, to modulate the immune response and
CC facilitate infection. Unlike the other paramyxovirus attachment
CC proteins, lacks both neuraminidase and hemagglutinating activities.
CC {ECO:0000250|UniProtKB:P03423}.
CC -!- FUNCTION: [Isoform Secreted glycoprotein G]: Helps the virus escape
CC antibody-dependent restriction of replication by acting as an antigen
CC decoy and by modulating the activity of leukocytes bearing Fc-gamma
CC receptors. {ECO:0000250|UniProtKB:P03423}.
CC -!- SUBUNIT: [Isoform Membrane-bound glycoprotein G]: Homooligomer.
CC Interacts (via N-terminus) with protein M. Part of a complex composed
CC of F1, F2 and G glycoproteins. Interacts with protein SH. Interacts
CC with host heparate sulfate; this interaction probably participates in
CC the viral attachment to the host cell. Interacts with host CX3CR1; this
CC interaction plays an important role in viral entry. Interacts with the
CC host lectins CD209/DC-SIGN and CD209L/L-SIGN on dendritic cells; these
CC interactions stimulate the phosphorylation of MAPK3/ERK1 and
CC MAPK1/ERK2, which inhibits dendritic cell activation and could
CC participate in the limited immunity against RSV reinfection.
CC {ECO:0000250|UniProtKB:P03423}.
CC -!- SUBCELLULAR LOCATION: [Isoform Membrane-bound glycoprotein G]: Virion
CC membrane {ECO:0000250|UniProtKB:P03423}; Single-pass type II membrane
CC protein {ECO:0000250|UniProtKB:P03423}. Host cell membrane
CC {ECO:0000250|UniProtKB:P03423}; Single-pass type II membrane protein
CC {ECO:0000250|UniProtKB:P03423}.
CC -!- SUBCELLULAR LOCATION: [Isoform Secreted glycoprotein G]: Secreted
CC {ECO:0000269|PubMed:3373568}. Note=The protein is shed from infected
CC cells before the appearance of progeny virus (PubMed:3373568). The
CC initiation at the downstream methionine removes a portion of the
CC transmembrane domain. The remaining hydrophobic portion of the sG
CC protein is essential for translocating it into the lumen of the ER
CC during translation and would likely maintain its membrane association
CC until a proteolytic event releases the mature sG protein into the
CC medium (Probable). {ECO:0000269|PubMed:3373568,
CC ECO:0000305|PubMed:3373568}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative initiation; Named isoforms=2;

CC IsoId=P20895-1; Sequence=Displayed;
CC Name=Secreted glycoprotein G;
CC IsoId=P20895-2; Sequence=VSP_036524;
CC -!- DOMAIN: [Isoform Membrane-bound glycoprotein G]: Contains a linear
CC heparin binding domain essential for virus attachment to the host.
CC {ECO:0000250|UniProtKB:P03423}.
CC -!- PTM: [Isoform Secreted glycoprotein G]: Cleaved to give rise to the
CC mature sG protein which lacks the transmembrane domain.
CC {ECO:0000269|PubMed:3373568}.
CC -!- SIMILARITY: Belongs to the pneumoviruses glycoprotein G family.
CC {ECO:0000305}.
CC -!- CAUTION: A second site of cleavage between residues 74 and 75 has been
CC described but has not been found in other strains.
CC {ECO:0000269|PubMed:3373568}.
