Protein
Non-canonical poly(A) RNA polymerase protein Trf4-1
Organism
Drosophila melanogaster
Function
Involved in a post-transcriptional quality control mechanism limiting inappropriate expression of genetic information (PubMed:18765642, PubMed:26786835). Polyadenylation is required for the degradative activity of the exosome on several of its nuclear RNA substrates (PubMed:26786835). Polyadenylates RNA processing and degradation intermediates of snRNAs and mRNAs (PubMed:18765642, PubMed:26786835).
Similarity
Belongs to the DNA polymerase type-B-like family.
