Ebolavirus GP functional and antigenic domain structure. (A) Full-length EBOV GP gene schematic indicating domains determined from structural analysis by color. Residues encompassing each domain are indicated by numbers. The 1-33 dotted domain is the non-structural signal peptide. Residues 313-464 are the mucin-like domain (MLD), which is disordered. The purple region from residues 190-214 represents the cathepsin cleavage loop, which hangs over the internal fusion loop (IFL) and is loosely ordered. (B) Surface rendering of EBOV GP (PDBID: 5JQ3) with corresponding domains shown in ribbon [based on numbering in part A, from Lee et al. (41)]. Antigenic sub-domains are indicated in bullet points. NPC1, Nieman Pick C1; MPER, membrane-proximal external region; TM, transmembrane domain. The structure of the MPER/TM is from PDBID: 5T42.
