An optimal range of transcription potency is necessary for efficient cell transformation by c-Rel to ensure optimal nuclear localization and gene-specific activation.

Abstract excerpt

c-Rel is overexpressed in several B-cell lymphomas and c-rel gene overexpression can transform primary chicken lymphoid cells and induce tumors in animals. Although c-Rel is generally a stronger transcriptional activator than its viral derivative v-Rel, its oncogenic activity is significantly weaker. Among the mutations acquired during c-Rel's evolution into v-Rel are deletion of c-Rel's transactivation domain 2...
