THOC4 (human)

Overview
THOC4 a chaperone protein that promotes the dimerization of transcription factors containing basic leucine zipper (bZIP) domains thus promoting transcriptional activation. Plays a role in mRNA processing and export. May function as scaffold that mediates interactions between proteins and/or RNA. Integral part of the THO/TREX complex that is recruited to transcribed genes and travels with the RNA polymerase during elongation. Is part of the exon junction complex that remains associated with spliced mRNA and plays an important role in mRNA export and nonsense-mediated RNA decay. Nuclear localization, translocates to the cytoplasm as part of the exon junction complex (EJC) bound to mRNA. Two differentially spliced isoforms have been described. Note: This description may include information from UniProtKB.
