  • RelevanceUPF3B is part of a post-splicing multiprotein complex involved in both mRNA nuclear export and mRNA surveillance. mRNA surveillance detects exported mRNAs with truncated open reading frames and initiates nonsense-mediated mRNA decay (NMD). When translation ends upstream from the last exon-exon junction, this triggers NMD to degrade mRNAs containing premature stop codons. UPF3B binds to the mRNA and remains bound after nuclear export, acting as a nucleocytoplasmic shuttling protein. It forms with Y14 a complex that binds specifically 20 nt upstream of exon-exon junctions. This gene is located on the long arm of chromosome X (referenced from entrez gene).
  • Cellular localizationNucleus. Cytoplasm. Note: Shuttling between the nucleus and the cytoplasm.

    Predicted band size : 57 kDa
    Observed band size : 52 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 35 kDa. We are unsure as to the identity of these extra bands.
