poly(rC) binding protein 2 recombinant protein epitope signature tag (PrEST)

General description

Poly (rC) binding protein 2 (PCBP2), also known as heterogeneous ribonuclear protein E2 (hnRNP E2) and αCP2, belongs to a group of proteins that bind to poly(C) stretches of both RNA and DNA and is encoded by the gene mapped to human chromosome 12q13.13. The encoded protein is a key constituent of stress granules (SG) and processing bodies (P-body). The protein shuttles between cytoplasm and nucleus.

Physical form

Solution in phosphate buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide.


All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Anti-PCBP2 antibody produced in rabbit has been used in fully automated and standardized-individual-nucleotide resolution cross-linking and immunoprecipitation (FAST- iCLIP).

Biochem/physiol Actions

Poly (rC) binding protein 2 (PCBP2) plays a vital role in controlling mRNA stability and regulating translation 14. In addition, it can also take part in protein-protein interactions. The encoded protein functions as a negative regulator of mitochondrial antiviral-signaling protein (MAVS)-mediated antiviral signaling via interacting with HECT (homologous to the E6-AP carboxyl terminus) domain -containing E3 ligase AIP4. Dysregulated expression of the gene results in oral cancer. PCBP2 plays a vital role as an initiator of internal ribosomal entry site (IRES)-mediated translation of both viral and cellular mRNA. Additionally, it also facilitates many biological processes, such as transcriptional regulation and translational silencing. Elevated expression of PCBP2 has been observed in human glioma tissues and cell lines. Downregulation of this gene, by the inhibition of cell-cycle progression and activation of caspase-3–mediated apoptosis, retards glioma growth in vitro and in vivo.
