Protein M2-1

UniProtKB accession:  Q4KRW3

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Acts as a tetrameric transcription processivity factor that binds in a competitive manner to RNA and the phosphoprotein (P) to prevent premature termination during transcription. Transcription anti-terminator that enhances readthrough of intergenic junctions during viral transcription. Preferentially binds to poly(A)-rich sequences. Plays a role in the association of the matrix protein with the nucleocapsid, which initiates assembly and budding. Also, can activate host NF-kappa-B through association with host RELA.
