| + | [https://www.uniprot.org/uniprot/GP_HANTV GP_HANTV] Glycoprotein N and Glycoprotein C interact with each. other and are present at the surface of the virion. They are able to attach the virion to host cell receptors. This attachment induces virion internalization predominantly through clathrin-dependent endocytosis. Also promote fusion of viral membrane with host endosomal membrane after endocytosis of the virion. Glycoprotein N contains an ITAM motif which is likely to dysregulate normal immune and endothelial cell responses and contribute to virus pathogenesis (By similarity).<ref>PMID:11886265</ref> | ||

| + | Hantaviruses are rodent-borne viruses causing serious zoonotic outbreaks worldwide for which no treatment is available. Hantavirus particles are pleomorphic and display a characteristic square surface lattice. The envelope glycoproteins Gn and Gc form heterodimers that further assemble into tetrameric spikes, the lattice building blocks. The glycoproteins, which are the sole targets of neutralizing antibodies, drive virus entry via receptor-mediated endocytosis and endosomal membrane fusion. Here we describe the high-resolution X-ray structures of the heterodimer of Gc and the Gn head and of the homotetrameric Gn base. Docking them into an 11.4-A-resolution cryoelectron tomography map of the hantavirus surface accounted for the complete extramembrane portion of the viral glycoprotein shell and allowed a detailed description of the surface organization of these pleomorphic virions. Our results, which further revealed a built-in mechanism controlling Gc membrane insertion for fusion, pave the way for immunogen design to protect against pathogenic hantaviruses. | ||
