Summaries for THOC2 Gene

Entrez Gene Summary for THOC2 Gene

  • The TREX multiprotein complex binds specifically to spliced mRNAs to facilitate mRNA export. The protein encoded by this gene is a member of the THO complex, a subset of the TREX complex. The encoded protein interacts with the THOC1 protein.[provided by RefSeq, Jun 2010]

GeneCards Summary for THOC2 Gene

THOC2 (THO Complex 2) is a Protein Coding gene. Diseases associated with THOC2 include mental retardation, x-linked 12/35 and peliosis hepatis. Among its related pathways are Gene Expression and RNA transport. GO annotations related to this gene include RNA binding.

UniProtKB/Swiss-Prot for THOC2 Gene

  • Required for efficient export of polyadenylated RNA and spliced mRNA. 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 Kaposis sarcoma-associated herpesvirus (KSHV) intronless mRNAs and infectious virus production. THOC2 (and probably the THO complex) is involved in releasing mRNA from nuclear speckle domains. Required for NXF1 localization to the nuclear rim. Plays a role for proper neuronal development.

THOC2_HUMAN
  • Mental retardation, X-linked 12 (MRX12) [MIM:300957]: A form of mental retardation, a disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. Intellectual deficiency is the only primary symptom of non-syndromic X-linked mental retardation, while syndromic mental retardation presents with associated physical, neurological and/or psychiatric manifestations. MRX12 patients manifest variable degrees of intellectual disability. Commonly observed features included speech delay, elevated BMI, short stature, seizure disorders, gait disturbance, and tremors. {ECO:0000269 PubMed:26166480}. Note=The disease is caused by mutations affecting the gene represented in this entry.
