Target

Function
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. Stimulates poly(A) polymerase (PAPOLA) conferring processivity on the poly(A) tail elongation reaction and controls also the poly(A) tail length. Increases the affinity of poly(A) polymerase for RNA. 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. Binds to poly(A) and to poly(G) with high affinity. May protect the poly(A) tail from degradation. -
Tissue specificity
Ubiquitous. -
Involvement in disease
Defects in PABPN1 are the cause of oculopharyngeal muscular dystrophy (OPMD) [MIM:164300]. OPMD is a form of late-onset slowly progressive myopathy characterized by eyelid ptosis, dysphagia and, sometimes by other cranial and limb-muscle involvement. -
Sequence similarities
Contains 1 RRM (RNA recognition motif) domain. -
Domain
The RRM domain is essential for specific adenine bases recognition in the poly(A) tail but not sufficient for poly(A) binding. -
Post-translational
modificationsArginine dimethylation is asymmetric and involves PRMT1 and PRMT3. It does not influence the RNA binding properties. -
Cellular localization
Nucleus. Cytoplasm. Localized in cytoplasmic mRNP granules containing untranslated mRNAs. Shuttles between the nucleus and the cytoplasm but predominantly found in the nucleus. Its nuclear import may involve the nucleocytoplasmic transport receptor transportin and a RAN-GTP-sensitive import mechanism. Is exported to the cytoplasm by a carrier-mediated pathway that is independent of mRNA traffic. Nucleus; nuclear speckle. Colocalizes with SKIP and poly(A) RNA in nuclear speckles. - Information by UniProt

Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 33 kDa
Observed band size: 44 kDa why is the actual band size different from the predicted?
Exposure time: 90 secondsThis blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 3% milk before being incubated with ab207515 overnight at 4°C. Antibody binding was visualised using ECL development solution ab133406.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - HRP Anti-PABPN1 antibody [EP3000Y] (ab207515)IHC image of PABPN1 staining in a section of formalin-fixed paraffin-embedded normal human testis tissue*, performed on a Leica BONDTM. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab207515, 1/100 dilution, for 15 mins at room temperature. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset negative control image is taken from an identical assay without primary antibody.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
