General annotation (Comments)

Function

Polymerase that creates the 3'-poly(A) tail of mRNA's. May acquire specificity through interaction with a cleavage and polyadenylation factor (CPSF).

Catalytic activity

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

Subunit structure

Monomer By similarity.

Subcellular location

Nucleus.

Sequence similarities

Belongs to the poly(A) polymerase family.
