[https://www.uniprot.org/uniprot/THOC1_HUMAN THOC1_HUMAN] Component of the THO subcomplex of the TREX complex. The TREX complex specifically associates with spliced mRNA and not with unspliced pre-mRNA. It 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. The recruitment occurs via an interaction between ALYREF/THOC4 and the cap-binding protein NCBP1. DDX39B functions as a bridge between ALYREF/THOC4 and the THO complex. The TREX complex is essential for the export of Kaposi's sarcoma-associated herpesvirus (KSHV) intronless mRNAs and infectious virus production. The recruitment of the TREX complex to the intronless viral mRNA occurs via an interaction between KSHV ORF57 protein and ALYREF/THOC4.<ref>PMID:10512864</ref> <ref>PMID:10840029</ref> <ref>PMID:11050087</ref> <ref>PMID:11979277</ref> <ref>PMID:15833825</ref> <ref>PMID:15998806</ref> <ref>PMID:15870275</ref> <ref>PMID:17190602</ref> <ref>PMID:18974867</ref> Regulates transcriptional elongation of a subset of genes. 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.<ref>PMID:10512864</ref> <ref>PMID:10840029</ref> <ref>PMID:11050087</ref> <ref>PMID:11979277</ref> <ref>PMID:15833825</ref> <ref>PMID:15998806</ref> <ref>PMID:15870275</ref> <ref>PMID:17190602</ref> <ref>PMID:18974867</ref> | |||
