Phosphoprotein

UniProtKB accession:  Q8B9Q8

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Plays critical roles in regulating RNA replication and transcription through its interactions with multiple proteins (By similarity). Tethers the RNA-directed RNA polymerase L to the nucleoprotein-RNA complex (PubMed:31698413). Recruits the M2-1 protein, a processivity factor that is required for efficient transcription of viral RNA (By similarity). Acts as a chaperone for neo-synthesized nucleoprotein by forming an N-P complex that preserves N in a monomeric and RNA-free state and prevents the association of nascent N with host cell RNAs (By similarity). Recruits the host phosphatase PP1 to inclusion bodies to regulate viral transcription (By similarity).
