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].

Zee (Verified Customer) (01-28-2020)

It worked very well when I performed western blot.

  • Applications: Western Blot,
  • Primary Antibody Dilution: 1:1000
  • Cell Tissue Type: Mouse heart tissue

George (Verified Customer) (09-11-2019)

Rb PABP Ig shows very little endogenous background staining with clear dispersed staining seen both in the nucleus and cytoplasm. 90mins heat shock at 42oC led to granular formation in the cytoplasm

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