CC -!- FUNCTION: Prevents the establishment of cellular antiviral state by
CC blocking the interferon-alpha/beta (IFN-alpha/beta) and IFN-gamma
CC signaling pathways. Blocks the IFN-induced nuclear accumulation of host
CC phosphorylated STAT1, by interacting with the STAT1-binding region of
CC host importin alpha-1/KPNA1 protein, thereby inhibiting the latter.
CC Without the activity of this protein, activated STAT1 would not enter
CC the nucleus and be unable to activate IFN-induced genes. Plays a role
CC in assembly of viral nucleocapsid and virion budding. May act as a
CC minor matrix protein that plays a role in assembly of viral
CC nucleocapsid and virion budding.
CC -!- SUBUNIT: Interacts with host importins KPNA1, KPNA5 and KPNA6
CC (PubMed:27974555). Interacts with host STAT1 (PubMed:22383882).
CC {ECO:0000269|PubMed:22383882, ECO:0000269|PubMed:27974555}.
CC -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000250}; Peripheral
CC membrane protein {ECO:0000250}. Host cell membrane {ECO:0000250};
CC Peripheral membrane protein {ECO:0000250}; Cytoplasmic side
CC {ECO:0000250}. Host endomembrane system {ECO:0000250}; Peripheral
CC membrane protein {ECO:0000250}. Note=In virion, localizes on the
CC intravirional side of the membrane. In the host cell, it is found
CC associated with virus-induced membrane proliferation foci and to the
CC plasma membrane where budding takes place (By similarity).
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the filoviridae membrane-associated protein VP24
CC family. {ECO:0000305}.
