"Study identified RANKL and BCL6 mRNA as targets of AUF1 p42. Detailed analysis of 3'UTRs revealed for both that full instability required two elements which are conserved in evolution. In RANKL mRNA both elements are AU-rich and separated by 30 bases while in BCL6 mRNA one is AU-rich and 60 bases from a non-AU-rich element that potentially forms a stem-loop structure."xsd:string
