Matrix protein

UniProtKB accession:  P08325

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Plays a major role in assembly and budding of virion. Condensates the ribonucleocapsid core during virus assembly. Shut off cellular transcription 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 (By similarity).
