Protein

Membrane-associated protein VP24

Gene

VP24

Organism
Zaire ebolavirus (strain Mayinga-76) (ZEBOV) (Zaire Ebola virus)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Prevents the establishment of cellular antiviral state by blocking the interferon-alpha/beta (IFN-alpha/beta) and IFN-gamma signaling pathways. Blocks the IFN-induced nuclear accumulation of host phosphorylated STAT1, by interacting with the STAT1-binding region of host importin alpha-1/KPNA1 protein, thereby inhibiting the latter. Without the activity of this protein, activated STAT1 would not enter the nucleus and be unable to activate IFN-induced genes. Plays a role in assembly of viral nucleocapsid and virion budding. May act as a minor matrix protein that plays a role in assembly of viral nucleocapsid and virion budding.4 Publications
