Protein
Pre-glycoprotein polyprotein GP complex
Organism
Guanarito mammarenavirus (isolate Human/Venezuela/NH-95551/1990)
Function
Stable signal peptide (SSP): cleaved and functions as a signal peptide. In addition, it is also retained as the third component of the GP complex. The SSP is required for efficient glycoprotein expression, post-translational maturation cleavage of GP1 and GP2, glycoprotein transport to the cell surface plasma membrane, formation of infectious virus particles, and acid pH-dependent glycoprotein-mediated cell fusion.
Similarity
Belongs to the arenaviridae GPC protein family.
