**Background of THOC1 Recombinant Protein**
THOC1 (THO Complex Subunit 1) is a critical component of the THO complex, a conserved eukaryotic protein assembly involved in transcription elongation, mRNA processing, and nuclear export of RNA molecules. The THO complex, comprising subunits THOC1–7 in humans, interacts with other mRNA export factors (e.g., Aly/REF and UAP56) to form the TREX (Transcription-Export) complex. This machinery ensures proper coupling of transcription with mRNA packaging and transport from the nucleus to the cytoplasm, essential for gene expression fidelity.
THOC1 specifically plays a role in stabilizing the complex and mediating interactions with RNA polymerase II during transcription. Dysregulation of THOC1 has been linked to developmental defects, neurological disorders, and cancer. For instance, reduced THOC1 expression correlates with poor prognosis in certain cancers, likely due to impaired mRNA export and genome instability.
Recombinant THOC1 protein is engineered using expression systems (e.g., *E. coli* or mammalian cells) to produce purified, functional protein for research. It enables *in vitro* studies on THO/TREX assembly, RNA-binding assays, and screening for inhibitors or interactors. Tags (e.g., His or GST tags) are often added for purification and detection. Researchers also use it to investigate THOC1’s role in diseases, offering potential insights into therapeutic targets.
Overall, THOC1 recombinant protein serves as a vital tool for dissecting mRNA metabolism mechanisms and their implications in health and disease.
