RL Submitted (DEC-2015) to the EMBL/GenBank/DDBJ databases.
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 {ECO:0000256|HAMAP-Rule:MF_00957}.
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; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_00957};
CC -!- SIMILARITY: Belongs to the tRNA nucleotidyltransferase/poly(A)
CC polymerase family. {ECO:0000256|HAMAP-Rule:MF_00957,
CC ECO:0000256|RuleBase:RU003953}.
