UniProtKB description: Structural component of the virion that interacts with glycoprotein C (PubMed:18715915). It shields the hydrophobic fusion loops of the glycoprotein C, preventing premature fusion (PubMed:29367607). The glycoprotein protrusions are arranged on an icosahedral lattice, with T=12 triangulation (PubMed:18715915, PubMed:29367607). They are able to attach the virion to the host cell receptor CD209/DC-SIGN and to promote fusion of membranes with the late endosome after endocytosis of the virion (PubMed:21767814). Plays a role in the packaging of ribonucleoproteins and polymerase during virus assembly (PubMed:21445316).
