Anti-PAB1 antibodies are protein reagents that detect specific antigens. The PAB1 antigen is another term for the human protein poly(A) binding protein cytoplasmic 1, encoded by the PABPC1 gene. The protein is known to bind 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. Canonically, it has an amino acid length of 636 residues and a mass of 70.7 kilodaltons. Its subcellular localization is in the nucleus and cytoplasm and it is ubiquitously expressed across many tissue types. The PAB1 protein is a member of the Polyadenylate-binding protein type-1 protein family. ELISA is a widely used application for the PAB1 antibodies listed below. In addition, Western Blot is also a common application.
