Target Background

Required for efficient export of polyadenylated RNA. Acts as component of the THO subcomplex of the TREX complex which is thought to couple mRNA transcription, processing and nuclear export, and which specifically associates with spliced mRNA and not with unspliced pre-mRNA. TREX is recruited to spliced mRNAs by a transcription-independent mechanism, binds to mRNA upstream of the exon-junction complex (EJC) and is recruited in a splicing- and cap-dependent manner to a region near the 5' end of the mRNA where it functions in mRNA export to the cytoplasm via the TAP/NFX1 pathway. The TREX complex is essential for the export of Kaposi's sarcoma-associated herpesvirus (KSHV) intronless mRNAs and infectious virus production. Regulates transcriptional elongation of a subset of genes. Involved in genome stability by preventing co-transcriptional R-loop formation.; Participates in an apoptotic pathway which is characterized by activation of caspase-6, increases in the expression of BAK1 and BCL2L1 and activation of NF-kappa-B. This pathway does not require p53/TP53, nor does the presence of p53/TP53 affect the efficiency of cell killing. Activates a G2/M cell cycle checkpoint prior to the onset of apoptosis. Apoptosis is inhibited by association with RB1.
Gene References into Functions
  1. THO interacts with the Sin3A histone deacetylase complex to suppress co-transcriptional R-loops, DNA damage, and replication impairment. Functional analyses show that histone hypo-acetylation prevents accumulation of harmful R-loops and RNA-mediated genomic instability. PMID: 29074626
  2. Colorectal cancer patients with high levels of Thoc1 expression had poorer overall-survival and disease-free survival, whereas those with lower levels of Thoc1 expression survived longer. PMID: 26545775
  3. In humans, high THOC1 protein expression associates with prostate cancer aggressiveness and recurrence. Thus, THOC1 protein is a molecular marker that may improve the identification of aggressive prostate cancers, potentially reducing overtreatment. PMID: 25296641
  4. Thoc1 inhibits cell growth via induction of cell cycle arrest and apoptosis in lung cancer cells. PMID: 24682263
  5. This suggests NEDD4-1 functions in conjunction with other post-translational mechanisms to regulate Thoc1 protein and THO activity. PMID: 23460917
  6. overexpression of hTREX84 is associated with cancer cell transformation, proliferation and may be regulated by RelA/p65 PMID: 22952718
  7. We show that human THO depletion impairs transcription elongation and mRNA export and increases instability associated with DNA breaks, leading to hyper-recombination and gammaH2AX and 53BP1 foci accumulation PMID: 22144908
  8. A differential connection between tumorogenesis and the expression levels of human THO and ALY. PMID: 21329510
  9. hHpr1/p84/Thoc1 regulates transcriptional elongation and may participate in a protein complex functionally analogous to yeast TREX, physically linking elongating RNA polymerase II with RNA processing factors PMID: 15870275
  10. recruitment of the human TREX complex to spliced mRNA is not directly coupled to transcription, but is instead coupled to transcription indirectly through splicing PMID: 15998806
  11. Thoc1 may be important for neoplastic transformation PMID: 17638875
  12. Cells respond to AAV infection by activating two DNA damage signaling cascades. The first activates the p84N5 protein, which in turn activates caspase-6, leading to cell death. PMID: 17699767
  13. elevated expression of hHpr1/p84/Thoc1 is common in NSCLC and may have prognostic significance in subgroups of patients PMID: 18469354
