ID:THOC5_HUMAN DESCRIPTION: RecName: Full=THO complex subunit 5 homolog; AltName: Full=Functional spliceosome-associated protein 79; Short=fSAP79; AltName: Full=NF2/meningioma region protein pK1.3; AltName: Full=Placental protein 39.2; Short=PP39.2; AltName: Full=hTREX90; FUNCTION: Component 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. 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 beteen KSHV ORF57 protein and ALYREF/THOC4. DDX39B functions as a bridge between ALYREF/THOC4 and the THO complex. THOC5 in conjunction with ALYREF/THOC4 functions in NXF1-NXT1 mediated nuclear export of HSP70 mRNA. Regulates the expression of myeloid transcription factors CEBPA, CEBPB and GAB2 by enhancing the levels of phosphatidylinositol 3,4,5-trisphosphate. May be involved in the differentiation of granulocytes and adipocytes. Essential for hematopoietic primitive cell survival and plays an integral role in monocytic development. SUBUNIT: Interacts with phosphorylated CSF1R and THOC1 (By similarity). Component of the THO complex, which is composed of THOC1, THOC2, THOC5, THOC6 and THOC7. Together with THOC3, ALYREF/THOC4 and DDX39B, THO forms the transcription/export (TREX) complex. Interacts with ALYREF/THOC4 and THOC7. Interacts (via N- terminus) with the NTF2 domain of NXF1. Forms a complex with CEBPB (By similarity). SUBCELLULAR LOCATION: Nucleus. Cytoplasm (By similarity). Note=Shuttles between nucleus and cytoplasm. TISSUE SPECIFICITY: Ubiquitously expressed. PTM: Phosphorylated on tyrosine upon binding to activated CSF1R; which causes a dissociation of the two proteins. Phosphorylation on Ser-5 and/or Ser-6 is required for nuclear export. Phosphorylated on Thr-328 in insulin-stimulated adipocytes (By similarity). Phosphorylated upon DNA damage, probably by ATM or ATR. SIMILARITY: Belongs to the THOC5 family. SEQUENCE CAUTION: Sequence=BAA76827.2; Type=Erroneous initiation; Note=Translation N-terminally shortened;
Genetic Association Studies of Complex Diseases and Disorders
Carotid atherosclerosis in HIV infection Shrestha ,et al. 2010, A genome-wide association study of carotid atherosclerosis in HIV-infected men, AIDS (London, England) 2009 .
These results suggest that in the context of HIV infection and HAART, a functional SNP in a biologically plausible candidate gene, RYR3, is associated with increased common carotid IMT, which is a surrogate for atherosclerosis.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.
ModBase Predicted Comparative 3D Structure on Q13769
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
