Overlay histogram showing HeLa cells stained with ab6125 (red line). The cells were fixed with 100% 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 (ab6125, 1μg/1x106 cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG2b [PLPV219] (ab91366, 2μg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in HeLa cells fixed with 4% paraformaldehyde (10 min)/permeabilized in 0.1% PBS-Tween used under the same conditions.

Supplementary information

PABP also known as Poly(A) Binding Protein is a significant component in mRNA metabolism. It binds to the poly(A) tail of eukaryotic mRNA molecules facilitating the translation process and aiding in mRNA stability. The protein is expressed ubiquitously throughout the cell with a mass of approximately 70 kDa. Some variations like PABPC1 exist in different contexts but the core functions remain consistent across these variations.
Biological function summary

This protein plays an essential role in translation initiation. PABP interacts with eukaryotic initiation factor 4G (eIF4G) which fosters the formation of the eIF4F complex an assembly critical for ribosome recruitment to mRNA. By linking the 5’ cap structure to the poly(A) tail PABP enhances translational efficiency and RNA integrity. Through these interactions it helps maintain normal cellular function and adapts to changes in the cellular environment.

Pathways

Poly(A) binding protein is central to the RNA metabolic process. It supports the canonical mRNA decay pathway by interacting with deadenylase complexes which initiate mRNA decay. Another key pathway involves the regulation of nonsense-mediated decay where PABP helps distinguish between normal and aberrant mRNAs. Proteins such as XRN1 and eIF4E closely interact with PABP to execute these pathways efficiently.

Issues with the poly(A) binding protein affect both cancer and neurodegenerative conditions. Aberrant expression or malfunction of PABP leads to defects in mRNA regulation potentially resulting in tumorigenesis due to disrupted cell cycle control. PABP also interacts with proteins like TDP-43 implicated in neurodegenerative diseases affecting RNA processing and potentially contributing to conditions like Amyotrophic Lateral Sclerosis (ALS). The consistent involvement of PABP in these processes highlights its importance to human health.

Target data

Binds the poly(A) tail of mRNA, including that of its own transcript, and regulates processes of mRNA metabolism such as pre-mRNA splicing and mRNA stability (PubMed : 11051545, PubMed : 17212783, PubMed : 25480299). Its function in translational initiation regulation can either be enhanced by PAIP1 or repressed by PAIP2 (PubMed : 11051545, PubMed : 20573744). Can probably bind to cytoplasmic RNA sequences other than poly(A) in vivo. Binds to N6-methyladenosine (m6A)-containing mRNAs and contributes to MYC stability by binding to m6A-containing MYC mRNAs (PubMed : 32245947). Involved in translationally coupled mRNA turnover (PubMed : 11051545). Implicated with other RNA-binding proteins in the cytoplasmic deadenylation/translational and decay interplay of the FOS mRNA mediated by the major coding-region determinant of instability (mCRD) domain (PubMed : 11051545). Involved in regulation of nonsense-mediated decay (NMD) of mRNAs containing premature stop codons; for the recognition of premature termination codons (PTC) and initiation of NMD a competitive interaction between UPF1 and PABPC1 with the ribosome-bound release factors is proposed (PubMed : 18447585). By binding to long poly(A) tails, may protect them from uridylation by ZCCHC6/ZCCHC11 and hence contribute to mRNA stability (PubMed : 25480299).. (Microbial infection) Positively regulates the replication of dengue virus (DENV).
