Preparation and Storage

Background: EBOV GP

The GP glycoprotein encoded by the genome of Ebola family viruses is a critical molecule for the pathogenicity of Ebolavirus hemorrhagic viruses (1, 2). It is processed into distinct forms for virus capsule or cell surface presentation or release from virus infected cells. The GP precursor protein is cleaved by furin at a multibasic site to yield a 140 kDa N-terminal fragment (GP1) and a 26 kDa C-terminal fragment (GP2) which remain disulfide linked (3). GP1 is entirely extracellular while GP2 is a transmembrane protein (4). Heterodimers of GP1-GP2 can further associate into trimers (5). GP expressed on virus infected cells can be shed by TACE mediated cleavage, liberating a disulfide linked complex of soluble GP1 and truncated GP2 (4-6). GP binds to multiple C-type lectins on target cell surfaces, including CLEC10A/MGL, DC-SIGN, and DC-SIGNR (7-9). Following internalization, GP1 is cleaved by Cathepsin B and Cathepsin L and then interacts with Niemann-Pick C1 (NPC1) in the endosomal membrane (10-12).
