Recombinant Mouse Tut1 Protein, Myc/DDK-tagged

• Cat.No.: Tut1-6738M
• Product Overview: Purified recombinant protein of mouse full-length terminal uridylyl transferase 1, U6 snRNA-specific (Tut1), with C-terminal MYC/DDK tag, expressed in HEK293T cells.

Specification

• Species: Mouse
• Source: HEK293
• Tag: DDK&Myc
• Description: Poly(A) polymerase that creates the 3'-poly(A) tail of specific pre-mRNAs. Localizes to nuclear speckles together with PIP5K1A and mediates polyadenylation of a select set of mRNAs, such as HMOX1. In addition to polyadenylation, it is also required for the 3'-end cleavage of pre-mRNAs: binds to the 3'UTR of targeted pre-mRNAs and promotes the recruitment and assembly of the CPSF complex on the 3'UTR of pre-mRNAs. In addition to adenylyltransferase activity, also has 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 for U6 snRNA in vitro: responsible for a controlled elongation reaction that results in the restoration of the four 3'-terminal UMP-residues found in newly transcribed U6 snRNA. Not involved in replication-dependent histone mRNA degradation.
