Comment

BCL3 is an atypical member of the IκB family. It is involved in immune cell differentiation and function [3] and it has been described as a proto-oncogene/oncoprotein that is associated with some cancers. Although the oncogenic nature of BCL3 was initially discovered in leukemia, it is also overexpressed in a number of solid tumours [1-2,4]. The design of small molecule inhibitors of BCL3 function, for use in oncology, is an active research focus for drug developers.
