PAP-alpha Polymerase that creates the 3'-poly(A) tail of mRNA's. Also required for the endoribonucleolytic cleavage reaction at some polyadenylation sites. May acquire specificity through interaction with a cleavage and polyadenylation specificity factor (CPSF) at its C-terminus. Belongs to the poly(A) polymerase family. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
