This data was developed using ab81224, the same antibody clone in a different buffer formulation.Overlay histogram showing HeLa cells stained with ab81224 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab81224, 1/100 dilution) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-rabbit IgG (H+L) (ab96899) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line). Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.

Supplementary information

PABPN1 also known as polyadenylate-binding nuclear protein 1 is an RNA-binding protein that plays a fundamental role in the regulation of mRNA processing. It is a 31-kilodalton protein that binds to the poly(A) tail of pre-mRNA and stimulates the assembly of the polyadenylation complex thereby influencing the maturation and stability of mRNA transcripts. This protein is predominantly expressed in the nucleus of eukaryotic cells where it performs its important function in post-transcriptional regulation.
Biological function summary

PABPN1 is involved in controlling the polyadenylation process of pre-mRNA which is essential for producing mature mRNA molecules. PABPN1 operates within a multi-protein complex that includes enzymes like poly(A) polymerase and cleavage stimulation factor (CstF). By interacting with these proteins PABPN1 ensures the correct formation of the 3' end of mRNA influencing gene expression regulation and mRNA stability.

Pathways

PABPN1 participates in key cellular pathways such as mRNA processing and nuclear export of mRNA. It operates in concert with other proteins like PABPC1 which aids in the transition of mRNA from the nucleus to the cytoplasm. The protein maintains the balance of mRNA stability and translation efficiency which are critical aspects of efficient gene expression.

PABPN1 mutations are linked to oculopharyngeal muscular dystrophy (OPMD) a genetic condition that leads to muscle weakness. Another related disorder involves its interaction with proteins like HSP70 where its dysfunction may contribute to disrupted protein homeostasis in affected tissues. Studying PABPN1's role in these diseases provides insight into the molecular mechanisms underlying these conditions and aids in the development of potential therapeutic strategies.

Target data

Involved in the 3'-end formation of mRNA precursors (pre-mRNA) by the addition of a poly(A) tail of 200-250 nt to the upstream cleavage product (By similarity). Stimulates poly(A) polymerase (PAPOLA) conferring processivity on the poly(A) tail elongation reaction and controls also the poly(A) tail length (By similarity). Increases the affinity of poly(A) polymerase for RNA (By similarity). Is also present at various stages of mRNA metabolism including nucleocytoplasmic trafficking and nonsense-mediated decay (NMD) of mRNA. Cooperates with SKIP to synergistically activate E-box-mediated transcription through MYOD1 and may regulate the expression of muscle-specific genes (PubMed : 11371506). Binds to poly(A) and to poly(G) with high affinity (By similarity). May protect the poly(A) tail from degradation (By similarity). Subunit of the trimeric poly(A) tail exosome targeting (PAXT) complex, a complex that directs a subset of long and polyadenylated poly(A) RNAs for exosomal degradation. The RNA exosome is fundamental for the degradation of RNA in eukaryotic nuclei. Substrate targeting is facilitated by its cofactor MTREX, which links to RNA-binding protein adapters (PubMed : 27871484).
