 -!- FUNCTION: Plays a major role in assembly and budding of virion, by
     recruiting cellular partners of the ESCRT complexes that play a
     key role in releasing the budding particle from the host membrane.
     Condensates the ribonucleocapsid core during virus assembly.
     {ECO:0000269|PubMed:16298982, ECO:0000269|PubMed:20943988}.
 -!- FUNCTION: Shut off cellular protein expression by inhibiting mRNA
     nuclear export through direct interaction with host RAE1-NUP98
     complex. This shutoff presumably inhibits interferon signaling and
     thus establishment of antiviral state in virus infected cells.
     Induces cell-rounding, cytoskeleton disorganization and apoptosis
     in infected cell. {ECO:0000269|PubMed:15629720}.
 -!- SUBUNIT: Homomultimer. Interacts with viral nucleocapsid.
     Interacts with host NEDD4 and TSG101 (PubMed:22190013). Interacts
     with host dynamin (PubMed:20943988). Interacts with host RAE1-
     NUP98 complex (PubMed:11106761, PubMed:15629720).
     {ECO:0000269|PubMed:11106761, ECO:0000269|PubMed:15629720,
     ECO:0000269|PubMed:20943988, ECO:0000269|PubMed:22190013}.
 -!- SUBCELLULAR LOCATION: Virion membrane; Peripheral membrane protein
     {ECO:0000269|PubMed:1850035}. Host endomembrane system; Peripheral
     membrane protein. Host nucleus membrane; Peripheral membrane
     protein.

       IsoId=P03519-3; Sequence=VSP_025420;
 -!- DOMAIN: Late-budding domains (L domains) are short sequence motifs
     essential for viral particle budding. They recruit proteins of the
     host ESCRT machinery (Endosomal Sorting Complex Required for
     Transport) or ESCRT-associated proteins. M contains two
     overlapping L domains: a PPXY motif which interacts with the WW
     domain 3 of NEDD4 and a PTAP/PSAP motif, which interacts with the
     UEV domain of TSG101. {ECO:0000269|PubMed:15220457,
     ECO:0000269|PubMed:16188963}.
 -!- PTM: Phosphorylated by host. {ECO:0000269|PubMed:1323702}.
 -!- BIOTECHNOLOGY: VSV is used as an oncolytic agent for cancer
     therapy, because of his wide host range, rapid replication and
     mild pathogenicity in humans. VSV used are mutated at M51R in
     their matrix protein. These mutated viruses cannot successfully
     infect normal cells, being unable to counteract the antiviral
     state induced by interferon-alpha in normal cells. Cancer cells
     are impeded with responsiveness to interferon, and then can be
     successfully infected and lysed by the virus.
 -!- MISCELLANEOUS: Most abundant protein in the virion.
 -!- SIMILARITY: Belongs to the vesiculoviruses matrix protein family.
