靶點(diǎn)詳情

  • 功能：
    Single-stranded nucleic acid binding protein that binds preferentially to oligo dC. Major cellular poly(rC)-binding protein. Binds also poly(rU). Negatively regulates cellular antiviral responses mediated by MAVS signaling. It acts as an adapter between MAVS and the E3 ubiquitin ligase ITCH, therefore triggering MAVS ubiquitination and degradation.; (Microbial infection) In case of infection by poliovirus, binds to the viral internal ribosome entry site (IRES) and stimulates the IRES-mediated translation. Also plays a role in initiation of viral RNA replication in concert with the viral protein 3CD.
  • 基因功能參考文獻(xiàn)：
    1. PCBP2 expression was markedly increased in higher stages of glioblastoma compared with those in lower stages; further research suggested that PCBP2 upregulation was connected with poorer prognosis in patients with glioblastoma PMID: 28787701
    2. Double immunofluorescence for hnRNP E2 and TDP-43 showed most TDP-43 immunopositive dystrophic neuritis within frontal and temporal cortex, and the neuronal cytoplasmic inclusions seen in dentate gyrus granule cells, to contain hnRNP E2. Present findings indicate an association between TDP-43 and hnRNP E2 which might underlie the pathogenetic mechanism of Semantic Dementia Frontotemporal Lobar Degeneration. PMID: 28666471
    3. Data suggest that the interaction between PCBP2 and the 3'UTR of the ARHGDIA mRNA may induce a local change in RNA structure that favors subsequent binding of miR-151-5p and miR-16, thus leading to the suppression of ARHGDIA expression. PMID: 26761212
    4. To promote intracellular iron flux, an iron chaperone appears to be essential for receiving iron from heme catabolism. Data suggest that PCBP2 competes with CPR for binding HO1; PCBP2 K homology 3 domain is important for HO1/PCBP2 interaction; heme prompts HO1/CPR multimer and decreases HO1/PCBP2 multimer. [PCBP2 = poly(rC) binding protein 2; CPR = cytochrome P450 reductase; HO1 = heme oxidase 1] PMID: 28655775
    5. Study determined that PCBP2 specifically associates with components of this kinase cascade and regulates the activities of its downstream transcriptional coactivators. PMID: 27215387

    7. PCBP2 was overexpressed in esophageal squamous cell carcinoma tissues and cell lines. PCBP2 expression promoted proliferation of ESCC cells.

    13. PCBP2-depletion induces apoptosis in gastric cancer cells via up-regulating expression of pro-apoptotic proteins and down-regulating anti-apoptotic proteins. miR-34a is a target of PCBP2, and miR-34a is critically essential for the function of PCBP2. PMID: 24796666
    14. SIRT6 inhibits glioma cell proliferation and colony formation in vitro and glioma cell growth in vivo in a PCBP2 dependent manner. SIRT6 inhibits PCBP2 expression through deacetylating H3K9ac and SIRT6 acts as a tumor suppressor in glioma. PMID: 24607900

    21. PCBP2 stabilizes the mRNA of STAT1 and STAT2 through binding the 3'Untranslated Region (UTR) of these two molecules. PMID: 22022391
    22. SRp75 inhibits splicing of tau exon 10 by binding to the CA repeat in the intronic splicing silencer downstream of the exon, and requires hnRNPG to exert its full regulatory effect on tau exon 10. PMID: 21723381
    23. study demonstrates the mechanism of the participation of PCBP2 in hepatitis C virus translation and replication PMID: 21632751
    24. Study reports that loss of miR-328 occurs in blast crisis chronic myelogenous leukemia (CML-BC) in a BCR/ABL dose- and kinase-dependent manner through the MAPK-hnRNP E2 pathway. PMID: 20211135
    25. The authors established that the 5'CL-PCBP complex is required for optimal poliovirus viral RNA translation and identified the KH3 domain of PCBP2 as the functional region. PMID: 19945132
    26. specific PCBP2 domains may have distinct roles for differential picornavirus template utilization during viral translation and RNA replication PMID: 12414943
