This entry represents the GP38 secreted glycoprotein from nairoviruses, including CCHFV and Dugbe virus. It is encoded in the glycoprotein precursor complex (GPC) from the M segment of nairovirus genome. It has a novel fold composed of a 3-helix bundle and a beta-sandwich [1,2]. Although its function is unknown, it is immunogenic in humans and, therefore, an interesting vaccine target [2].
The medium (M) genome segment of hantaviruses (family Bunyaviridae) encodes the two virion glycoproteins [1,2] Gn and Gc (also known as G1 and G2, respectively) as a polyprotein precursor. Gn and Gc forms homotetramers at the surface of the virion, w ...
The medium (M) genome segment of hantaviruses (family Bunyaviridae) encodes the two virion glycoproteins [1,2] Gn and Gc (also known as G1 and G2, respectively) as a polyprotein precursor. Gn and Gc forms homotetramers at the surface of the virion, which attach the virion to host cell receptors including integrin beta3/ITGB3 and induce internalisation, predominantly through clathrin-dependent endocytosis [3,4]. This protein has a typical class II fusion protein fold consisting of a central beta-sandwich domain (termed domain I) made of eight beta-strands arranged in two antiparallel beta-sheets; domain II which has an elongated shape with two subdomains (a central, opened beta-barrel proximal to domain I and a distal beta-sandwich 'tip') and the C-terminal domain III, represented in this entry, which has a Ig-like fold [1,2].
