The medium (M) genome segment of hantaviruses (family Bunyaviridae) encodes the two virion glycoproteins, Gn and Gc (also known as G1 and G2, respectively), as a polyprotein precursor [1,2,3]. Gn and Gc forms homotetramers (spikes) at the surface of the virion which attach the virion to host cell receptors including integrin beta3/ITGB3 induce internalisation, predominantly through clathrin-dependent endocytosis [3,4]. This entry represents the N-terminal two-thirds of the Gn glycoprotein ectodomain, denoted as 'head' (Gn-H) [2] which interacts with Gc ectodomain. Release of Gn-H at acid pH induces a further conformational change of the Gc domain II tip which exposes non-polar side chains for insertion into the endosomal membrane [2].	Domain
