CC   -!- FUNCTION: Plays a major role in assembly, budding and uncoating of
CC       virion after membrane fusion. Completely covers the ribonucleoprotein
CC       coil and keep it in condensed bullet-shaped form. Inhibits viral
CC       transcription and stimulates replication. Plays a major role in early
CC       induction of TRAIL-mediated apoptosis in infected neurons.
CC       {ECO:0000250|UniProtKB:P16287}.
CC   -!- SUBUNIT: Homomultimer. Interacts with nucleoprotein and with the
CC       cytoplasmic domain of glycoprotein. Interacts with host ATP6V1A; this
CC       interaction plays an important role in virion uncoating after viral
CC       entry. {ECO:0000250|UniProtKB:P16287}.
CC   -!- INTERACTION:
CC       P0DOF2; P38606: ATP6V1A; Xeno; NbExp=10; IntAct=EBI-25567776, EBI-1054757;
CC   -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000250|UniProtKB:P16287};
CC       Peripheral membrane protein {ECO:0000250|UniProtKB:P16287}. Host
CC       endomembrane system {ECO:0000250|UniProtKB:P16287}; Peripheral membrane
CC       protein {ECO:0000250|UniProtKB:P16287}. Host cytoplasm
CC       {ECO:0000250|UniProtKB:P16287}.
CC   -!- DOMAIN: Late-budding domains (L domains) are short sequence motifs
CC       essential for viral particle budding. They recruit proteins of the host
CC       ESCRT machinery (Endosomal Sorting Complex Required for Transport) or
CC       ESCRT-associated proteins. Matrix protein contains one L domain: a PPXY
CC       motif which potentially interacts with the WW domain 3 of NEDD4 E3
CC       ubiquitin ligase (Potential). {ECO:0000305}.
CC   -!- MISCELLANEOUS: Most abundant protein in the virion. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the lyssavirus matrix protein family.
CC       {ECO:0000305}.
