BCL3 Encodes a Nuclear Protein Which Can Alter the Subcellular Location of NF-κB Proteins

Abstract excerpt

BCL3 is a candidate proto-oncogene involved in the recurring translocation t(14;19) found in some patients with chronic lymphocytic leukemia. BCL3 protein acts as an I kappa B in that it can specifically inhibit the DNA binding of NF-kappa B factors. Here, we demonstrate that BCL3 is predominantly a nuclear protein and provide evidence that its N terminus is necessary to direct the protein into the nucleus. In...
