Influence of HuR and its Protein Ligand APRIL on CD83 Expression

Prof. Dr. Joachim Hauber (Heinrich-Pette-Institut)

It has been shown that CD83 mRNA is transported from the nucleus to the cytoplasm by an uncommon route, involving the cellular RNA-binding protein HuR and the nuclear export receptor CRM1. Here, we are able to report that casein kinase 2 (CK2) phosphorylates the HuR ligand APRIL and demonstrate that this phosphorlyation is essential for nucleocytoplasmic translocation of CD83 mRNA.
