Overview of Lassa virus glycoprotein. The primary translation product of Lassa virus glycoprotein (pre-GP-C; amino acids (aa) 1–491), the signal peptide (SP; aa 1–58), the precursor glycoprotein (GP-C; aa 59–491), the distal subunits GP1 (aa 59–259) and GP2 (aa 260–491) containing the membrane anchor (aa 427–450, stripes) are shown. Antisera binding sites, Rb-α-SP (aa 2-18) and Rb-α-GP2-N (aa 259–277), the signal peptidase (SPase) cleavage site between threonine residues 58 and 59 (arrow), the SKI1/S1P (subtilisin-kexin isoenzyme 1/site 1 protease) cleavage site carboxy-terminal of leucine 259 (arrow) and putative N-glycosylation sites (Y symbols) are indicated. The total signal peptide sequence is shown in one-letter code at the bottom of the figure.
