Keap1 is a protein that degrades the transcription factor Nrf2(4). VP24 in the Marburg virus targets and binds the Keap1 protein, and as a result leaves Nrf2 unaltered(4). High levels of Nrf2 triggers antioxidant response elements(ARE)(4). This causes cells to become defensive, which protects the Marburg virus inside the cell(4).

The Ebola and Marburg VP24 proteins are 30% identical(1). They share a similar pyramidal shaped domain, as well as a few structures. Both viruses have two highly conserved pockets underneath the "pyramid's" base <ref name='Marburg '/>. Additionally, the N termini of Ebola (Zaire) and the Marburg virus are very similar in function. They are both used for oligomer and nucleocapsid formation <ref name='Marburg '/><ref>pmid 22371572</ref>.
