Eukaryotic Gene Regulation and Quality Control The Gehring lab is interested in different aspects of gene expression regulation at the post-transcriptional level. We analyse the functions of RNA-binding protein complexes that are involved in: mRNA export mRNA quality control mRNA regulation mRNA Biology: Eukaryotic Gene Regulation and Quality Control Processing of mRNAs, formation and function of exon junction complexes Formation of export competent mRNPs, function of mRNA export proteins  Nonsense-mediated mRNA decay, detection and degradation of aberrant transcripts
