Background Information

The poly(A)-binding protein (PABP), which is found complexed to the 3-prime poly(A) tail of eukaryotic mRNA, is required for poly(A) shortening and translation initiation [PMID: 21989405]. Polyadenylate-binding protein 1 (PABPC1) is a cytoplasmic-nuclear shuttling protein important for protein translation initiation, and both RNA processing and stability. In the cytoplasm, PABPC1 binds to the 3' poly(A) tail of eukaryotic mRNAs through its RNA-recognition motifs (RRM) and interacts with the N-terminus of eIF4G, part of the eIF4F complex associated with the 5' cap structure [PMID:20009508, 17381337].

PABPC1 (Poly(A) Binding Protein Cytoplasmic 1) staining (in magenta) and Hoechst (nuclear staining) in blue. PABPC1 ab shows a clear citoplasma staining. Method: RPE1 cells were fixed in cold methanol for 10' at -20C. Cells were then rehydrated with PBS for 5'. Membrane permeabilization was then performed with 0.1% Triton + 0.1% Tween +0.01%SDS in PBS for 10'. Cells were finally incubated with blocking buffer (5% BSA+ 0.1% Tween in PBS) for 30' at RT. Primary antibody was diluted in blocking buffer 1:200 and incubated for 1h at room temperature. Alexa-488-Anti-rabbit was used as secondary antibody (1:600 dilution) (1h at room temperature).

  • Primary Antibody Dilution: 1:100
  • Cell Tissue Type: Spinal Cord/Cortical Slice Culture
