AC MF_00957; DC Protein; auto TR HAMAP; MF_00957; -; 1; level=0 XX Names: PolyA_pol XX ID PCNB DE RecName: Full=Poly(A) polymerase I; DE Short=PAP I; DE EC=2.7.7.19; GN Name=pcnB; XX CC -!- FUNCTION: Adds poly(A) tail to the 3' end of many RNAs, which usually CC targets these RNAs for decay. Plays a significant role in the global CC control of gene expression, through influencing the rate of transcript CC degradation, and in the general RNA quality control. CC -!- CATALYTIC ACTIVITY: CC Reaction=ATP + RNA(n) = diphosphate + RNA(n)-3'-adenine ribonucleotide; CC Xref=Rhea:RHEA:11332, Rhea:RHEA-COMP:14527, Rhea:RHEA-COMP:17347, CC ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:140395, CC ChEBI:CHEBI:173115; EC=2.7.7.19; CC -!- SIMILARITY: Belongs to the tRNA nucleotidyltransferase/poly(A) CC polymerase family.
