Marburg Virus Envelope Glycoprotein

The Marburg virus (MARV) Envelope Glycoprotein (GP) is a transmembrane protein that protrudes from the surface of MARV virions, where it plays a critical role in mediating receptor recognition and entry to target cells. GP is translated at the rough endoplasmic reticulum, where it hijacks the secretory pathway, crossing the endoplasmic reticulum, Golgi apparatus, and trans-Golgi network to reach the plasma membrane, where it is incorporated into budding viral particles.

Marburg Virus Envelope Glycoprotein Diagram

As GP passes through the trans-Golgi network, it is acylated, glycosylated and proteolytically cleaved by furin into two subunits, GP1 and GP2, which assemble together at the membrane to form the functional GP protein. In addition to GP and these two subunits, multiple other forms of protein are produced during infection, the functions of which are not yet clear.

The Native Antigen Company now offers Marburg virus Envelope Glycoprotein, presented as a mix of uncleaved GP and cleaved GP1 and GP2 subunits, as shown by SDS-PAGE. Expressed from our proprietary HEK293 expression system, these proteins are fully acylated and glycosylated to ensure proper folding and presentation of native epitopes.
