CC   -!- FUNCTION: Required for efficient export of polyadenylated RNA. Acts as
CC       component of the THO subcomplex of the TREX complex which is thought to
CC       couple mRNA transcription, processing and nuclear export, and which
CC       specifically associates with spliced mRNA and not with unspliced pre-
CC       mRNA. TREX is recruited to spliced mRNAs by a transcription-independent
CC       mechanism, binds to mRNA upstream of the exon-junction complex (EJC)
CC       and is recruited in a splicing- and cap-dependent manner to a region
CC       near the 5' end of the mRNA where it functions in mRNA export to the
CC       cytoplasm via the TAP/NFX1 pathway. Regulates transcriptional
CC       elongation of a subset of genes. Involved in genome stability by
CC       preventing co-transcriptional R-loop formation (By similarity).
CC       {ECO:0000250}.
CC   -!- FUNCTION: Participates in an apoptotic pathway which is characterized
CC       by activation of caspase-6, increases in the expression of BAK1 and
CC       BCL2L1 and activation of NF-kappa-B. This pathway does not require
CC       p53/TP53, nor does the presence of p53/TP53 affect the efficiency of
CC       cell killing. Activates a G2/M cell cycle checkpoint prior to the onset
CC       of apoptosis. Apoptosis is inhibited by association with RB1 (By
CC       similarity). Essential for early embryonic development. Required for
CC       normal gene expression during postnatal testis development.
CC       {ECO:0000250, ECO:0000269|PubMed:16705185,
CC       ECO:0000269|PubMed:19307311}.
CC   -!- SUBUNIT: Component of the THO complex, which is composed of THOC1,
CC       THOC2, THOC3, THOC5, THOC6 and THOC7; together with at least
CC       ALYREF/THOC4, DDX39B, SARNP/CIP29 and CHTOP, THO forms the
CC       transcription/export (TREX) complex which seems to have a dynamic
CC       structure involving ATP-dependent remodeling. Binds to the
CC       hypophosphorylated form of RB1. Interacts with THOC2, DDX39B and RNA
CC       polymerase II (By similarity). Interacts with THOC5 (PubMed:16909111).
CC       Interacts with LUZP4 (By similarity). {ECO:0000250|UniProtKB:Q96FV9,
CC       ECO:0000269|PubMed:16909111}.
CC   -!- SUBCELLULAR LOCATION: Nucleus speckle {ECO:0000250}. Nucleus,
CC       nucleoplasm {ECO:0000269|PubMed:16705185}. Nucleus matrix
CC       {ECO:0000250}. Cytoplasm {ECO:0000250}. Note=Can shuttle between the
CC       nucleus and cytoplasm. Nuclear localization is required for induction
CC       of apoptotic cell death. Translocates to the cytoplasm during the early
CC       phase of apoptosis execution (By similarity). {ECO:0000250}.
CC   -!- DEVELOPMENTAL STAGE: Widely expressed during embryonic development.
CC       {ECO:0000269|PubMed:16705185}.
CC   -!- DOMAIN: An intact death domain is needed for apoptosis. {ECO:0000250}.
CC   -!- PTM: Expression is altered specifically during apoptosis and is
CC       accompanied by the appearance of novel forms with smaller apparent
CC       molecular mass. {ECO:0000250}.
CC   -!- PTM: Polyubiquitinated, leading to proteasomal degradation; probably
CC       involves NEDD4. {ECO:0000250}.
CC   -!- DISRUPTION PHENOTYPE: Mice show early embryonic lethality and severely
CC       diminished fertility. {ECO:0000269|PubMed:16705185,
CC       ECO:0000269|PubMed:19307311}.
