Protein
Speckle targeted PIP5K1A-regulated poly(A) polymerase
Gene

Organism
Ailuropoda melanoleuca (Giant panda)
Status
Reviewed - Annotation score: 5 out of 5 - Protein inferred from homologyi

Functioni

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 By similarity.

Catalytic activityi

UTP + RNA(n) = diphosphate + RNA(n+1).
ATP + RNA(n) = diphosphate + RNA(n+1).

Cofactori

Magnesium or manganese By similarity.

Enzyme regulationi

Adenylyltransferase activity is specifically phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2) By similarity.
