Keap1 is a protein that degrades the transcription factor Nrf2 | Keap1 is a protein that degrades the transcription factor Nrf2. VP24 in the Marburg virus targets and binds the Keap1 protein, and as a result leaves Nrf2 unaltered. High levels of Nrf2 triggers antioxidant response elements(ARE). This causes cells to become defensive, which protects the Marburg virus inside the cell <ref>do 10.1016/j.celrep.2014.01.043</ref>. | ||

The Ebola and Marburg VP24 proteins are 30% identical | The Ebola and Marburg VP24 proteins are 30% identical <ref name='Marburg '/>. 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>. | ||
