Identifier
LTACT
Protein name
RecName: Full=Late transcription coactivator;
AltName: Full=RNA polymerase-associated protein Gp33;

Comments [?]

Function Activates transcription at late promoters when the sliding clamp is present. Binds to both the host RNA polymerase (RNAP) and the upstream dsDNA.
Subunit Interacts with the beta subunit of host RNAP RpoB (via flap domain). Part of the transcription activation complex containing host RNAP, the viral RNA polymerase sigma-like factor, the coactivator gp33, and the sliding clamp.
Domain The C-terminus is involved in transcriptional enhancement.
Similarity Belongs to the Tevenvirinae late transcription coactivator family.

Gene Ontology [?]

GO:0140537; Molecular function: transcription regulator activator activity.
GO:0019086; Biological process: late viral transcription.
