Description

Mouse Monoclonal Antibody

Anti-PCBP2 (hnRNP E2), clone PC81-1, Cat. No. MABF2122, is a mouse monoclonal antibody that detects Poly(rC)-binding protein 2 and has been tested for use in Immunocytochemistry and Western Blotting.

Poly(rC)-binding protein 2 (UniProt: Q15366; also known as Alpha-CP2, Heterogeneous nuclear ribonucleoprotein E2, hnRNP E2) is encoded by the PCBP2 gene (Gene ID: 5094) in human. PCBP2 belongs to a class of cellular proteins that bind to poly(C) stretches of both RNA and DNA and has been detected in all tissues studied. PCBP2 shuttles between the nucleus and cytoplasm and exerts its impact on RNA processing and mRNA expression through sequence-specific interactions with C-rich determinants within target mRNAs. It acts as an important mediator of multiple processes, including replication of viruses with gastrointestinal and hepatic tropism, hepatic collagen synthesis, globin expression, and cellular proliferation. PCBP2 is shown to negatively regulate cellular antiviral responses mediated by mitochondrial antiviral-signaling protein (MAVS) signaling and acts as an adapter between MAVS and the E3 ubiquitin ligase ITCH, thereby triggering MAVS ubiquitination and degradation. Together with PCBP1, it is shown to function as a translational coactivator of poliovirus RNA via a sequence-specific interaction with stem-loop IV of the IRES, promoting poliovirus RNA replication. It has also been implicated in translational control of the 15-lipoxygenase mRNA, human papillomavirus type 16 L2 mRNA, and hepatitis A virus RNA. PCBP2 contains three K-homologous (KH) domains that mediates poly(C) binding. Eight different isoforms of PCBP2 have been described that are produced by alternative splicing. (Ref.: Ghanem, LR et al.
