Function
[M21_HRSVA] Acts as a transcriptional elongation factor to prevent premature termination during transcription thus allowing complete synthesis of RSV mRNAs. Functions also as a processivity and antitermination factor to permit transit of the polymerase through intergenic regions to access promoter distal genes. Plays a role in the association of the matrix protein with the nucleocapsid, which initiates assembly and budding. Also, can activate NF-kappa-B through association with host RELA.[1] [2] [3]
