Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Function

Adds poly(A) tail to the 3' end of many RNAs, which usually targets these RNAs for decay. Plays a significant role in the global control of gene expression, through influencing the rate of transcript degradation, and in the general RNA quality control By similarity. HAMAP-Rule MF_00957

Catalytic activity

ATP + RNA(n) = diphosphate + RNA(n+1). HAMAP-Rule MF_00957

Sequence similarities

Belongs to the tRNA nucleotidyltransferase/poly(A) polymerase family.

Sequence caution

The sequence AAN78670.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
