Structural highlights
FunctionGP_SFTS Structural component of the virion that interacts with glycoprotein C (By similarity). It shields the hydrophobic fusion loops of the glycoprotein C, preventing premature fusion (By similarity). The glycoprotein protrusions are arranged on an icosahedral lattice, with T=12 triangulation (By similarity). 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 clathrin-mediated endocytosis of the virion (PubMed:23388721). Plays a role in the packaging of ribonucleoproteins during virus assembly (By similarity).[UniProtKB:P09613][UniProtKB:P21401][1] Structural component of the virion that interacts with glycoprotein N (By similarity). Acts as a class II fusion protein that is activated upon acidification and subsequent repositioning of the glycoprotein N (By similarity). The glycoprotein protrusions are arranged on an icosahedral lattice, with T=12 triangulation (By similarity). 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 clathrin-mediated endocytosis of the virion (PubMed:23388721).[UniProtKB:P09613][UniProtKB:P21401][2] References
