The NF-?B transcriptional response is tightly regulated by a number of processes
including the phosphorylation, ubiquitination, and subsequent proteasomal
degradation of NF-?B subunits. The I?B family protein BCL-3 stabilizes a NF-?B
p50 homodimer·DNA complex through inhibition of p50 ubiquitination. This complex
inhibits the binding of the transcriptionally active NF-?B subunits p65 and c-Rel
on the promoters of NF-?B target genes and functions to suppress inflammatory
gene expression. We have previously shown that the direct interaction between p50
and BCL-3 is required for BCL-3-mediated inhibition of pro-inflammatory gene
expression. In this study we have used immobilized peptide array technology to
define regions of BCl-3 that mediate interaction with p50 homodimers. Our data
show that BCL-3 makes extensive contacts with p50 homodimers and in particular
with ankyrin repeats (ANK) 1, 6, and 7, and the N-terminal region of Bcl-3. Using
these data we have designed a BCL-3 mimetic peptide based on a region of the ANK1
of BCL-3 that interacts with p50 and shares low sequence similarity with other
I?B proteins. When fused to a cargo carrying peptide sequence this BCL-3-derived
peptide, but not a mutated peptide, inhibited Toll-like receptor-induced cytokine
expression in vitro. The BCL-3 mimetic peptide was also effective in preventing
inflammation in vivo in the carrageenan-induced paw edema mouse model. This study
demonstrates that therapeutic strategies aimed at mimicking the functional
activity of BCL-3 may be effective in the treatment of inflammatory disease.
