Protein detail:


Protein name Attachment glycoprotein
Uniprot protein ID P03423
Protein length 298 amino acids
Protein description G protein is another target for neutralizing antibodies and it is a type II integral membrane protein composed of 298AA and weights ~ 90 kDa. It is vastly glycosylated and it is expressed in secreted and membrane-anchored forms called Gs and Gm, respectively. Gs is linked to neutralization inhibition, while Gm is related to viral attachment. This hostvirus membrane attachment is mediated by heparin sulfate proteoglycans receptor interaction. The antigenic variation is situated in the mucin domain of G protein at both C- and N- terminal ends. N- and O-glycosylation enables the protein to mature and enhances immune escape mechanisms. Other feature includes a central conserved region (CX3C motif) which is responsible for CX3CR1 binding to diminish inflammatory cytokines release.
