Summary
PAPOLA (poly(A) polymerase alpha, HGNC:14981) is a protein-coding gene on chromosome 14q32.2, encoding Poly(A) polymerase alpha (P51003). Polymerase that creates the 3’-poly(A) tail of mRNA’s.
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.

Literature-anchored findings (GeneRIF, showing 5)
- Observations imply that translational regulation is among the conserved mechanisms regulating PAPOLA expression. (PMID:20174964)
- The ability of PABPN1 to promote splicing requires its RNA binding and, to a lesser extent, poly(A)polymerase (PAP) - stimulatory functions. (PMID:25896913)
- Lack of CstF-64 binding excludes PAPalpha from Star-PAP target pre-mRNA UTRs.CstF-64 and 3’-UTR cis-element determine Star-PAP specificity for target mRNA selection by excluding poly A polymerase. (PMID:26496945)
- Whereas PABPN1 strongly increases the activity of its cognate poly(A) polymerase in vitro, Pab2 was unable to stimulate Pla1 to any significant extent. (PMID:28096519)
- PAPOLA contributes to cyclin D1 mRNA alternative polyadenylation and promotes breast cancer cell proliferation. (PMID:33712453)

Function. 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.
Subunit / interactions. Monomer. Found in a complex with CPSF1, FIP1L1 and PAPOLA. Interacts with AHCYL1 and FIP1L1; the interaction with AHCYL1 seems to increase interaction with FIP1L1. Interacts with NUDT21; the interaction is diminished by acetylation. Interacts with KPNB1; the interaction promotes PAP nuclear import and is inhibited by acetylation of PAP.
Subcellular location. Cytoplasm. Nucleus.
Post-translational modifications. Polysumoylated. Varying sumoylation depending on tissue- and cell-type. Highly sumoylated in bladder and NIH 3T3 cells. Sumoylation is required for nuclear localization and enhances PAP stability. Desumoylated by SENP1. Inhibits polymerase activity. Hyperphosphorylation on multiple CDK2 consensus and non-consensus sites in the C-terminal Ser/Thr-rich region represses PAP activity in late M-phase. Phosphorylation/dephosphorylation may regulate the interaction between PAP and CPSF. Acetylated in the C-terminus. Acetylation decreases interaction with NUDT21 and KPNB1, and inhibits nuclear localization through inhibiting binding to the importin alpha/beta complex.
Cofactor. Binds 2 magnesium ions. Also active with manganese.
Similarity. Belongs to the poly(A) polymerase family.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 39 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
