  Function in Host
Poly (A) polymerase that creates the 3'-poly (A) tail ofspecific pre-mRNAs. Localizes tonuclear speckles together with PIP5K1A and mediates polyadenylation ofa select set of mRNAs, such as HMOX1. In addition topolyadenylation, it is also required for the 3'-end cleavage of pre-mRNAs: binds to the 3'UTR of targeted pre-mRNAs and promotes therecruitment and assembly of the CPSF complex on the 3'UTR of pre-mRNAs. In addition to adenylyltransferase activity, alsohas uridylyltransferase activity. However, the ATP ratio is higher than UTP in cells, suggesting that it functions primarily as a poly (A) polymerase. Acts as a specific terminal uridylyltransferase forU6 snRNA in vitro: responsible for a controlled elongation reactionthat results in the restoration of the four 3'-terminal UMP-residuesfound in newly transcribed U6 snRNA. Not involved in replication-dependent histone mRNAdegradation. [1-4]

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Anti-viral [5]
Infected TissueLung Infection Time7-9 Days
Infected CellCalu-3 Cells (Human epithelial cell line) Cellosaurus IDCVCL_0609 
Method DescriptionTo detect the role of host protein TUT1 in viral infection, TUT1 protein knockdown Calu-3 Cells were infected with SARS-COV-2 for 7 - 9 Days , and the effects on infection was detected through CRISPR-based genome-wide gene-knockout screen.
ResultsIt is reported that knockout of TUT1 increases SARS-CoV-2 RNA levels compared with control group.
