Poly(A) polymerase alpha is an enzyme that in humans is encoded by the PAPOLA gene.
The protein encoded by this gene belongs to the poly(A) polymerase family. It is required for the addition of adenosine residues for the creation of the 3'-poly(A) tail of mRNAs. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011].

Poly(A) polymerase alpha is an enzyme that in humans is encoded by the PAPOLA gene.
PAPOLA binds to FIP1L1 (Factor interacting with PAPOLA and CPSF1), a subunit of the cleavage and polyadenylation specificity factor subunit 1 (CPSF1) complex. This complex polyadenylates the 3' end of precursor mRNAs (pre-mRNA) (see CPSF). CPSF1 is an RNA processing protein that binds to uracil-rich sequences in pre-mRNA, binds with and stimulates PAPOLA's Polynucleotide adenylyltransferase activity, and thereby adds adenylyl residues to pre-mRNA. This poly-adenylyl action increases pre mRNA's maturation and movement from the nucleus to cytoplasm while dramatically increasing the stability of the mRNA formed from pre-mRNA: FIP1L1 is a Pre-mRNA 3'-end-processing factor. FIP1L1 gene fusions between it and either the platelet-derived growth factor receptor, alpha (PGDFRA) or Retinoic acid receptor alpha (RARA) genes are causes of certain human diseases associated with pathologically increased levels of blood eosinophils and/or Leukemias.
