Function
function
Attaches the virion to the host cell membrane by interacting with heparan sulfate, initiating the infection. Interacts with host CX3CR1, the receptor for the CX3C chemokine fractalkine, to modulate the immune response and facilitate infection. Unlike the other paramyxovirus attachment proteins, lacks both neuraminidase and hemagglutinating activities.
Isoform Secreted glycoprotein G
Helps the virus escape antibody-dependent restriction of replication by acting as an antigen decoy and by modulating the activity of leukocytes bearing Fc-gamma receptors.

Interaction
Subunit
Homooligomer. Interacts (via N-terminus) with protein M. Part of a complex composed of F1, F2 and G glycoproteins. Interacts with protein SH. Interacts with host heparate sulfate; this interaction probably participates in the viral attachment to the host cell. Interacts with host CX3CR1; this interaction plays an important role in viral entry. Interacts with the host lectins CD209/DC-SIGN and CD209L/L-SIGN on dendritic cells; these interactions stimulate the phosphorylation of MAPK3/ERK1 and MAPK1/ERK2, which inhibits dendritic cell activation and could participate in the limited immunity against RSV reinfection.
