NF-κB is a transcription factor for the immune activation and tissue stability, but excess activation of NF-κB often causes inflammation and cancer. An NF-κB component RelB is involved in B-cell maturation and autoimmunity. In the present research we studied the role of the RelB DNA binding domain on cellular stability and importin affinity. We prepared a(More)
Fluorometric titration of E. coli single-stranded DNA binding protein with various RNAs showed that the protein specifically and cooperatively binds to its own mRNA. The binding inhibited in vitro expression of ssb and bla but not nusA. This inhibition takes place at a physiological concentration of SSB. The function of the protein in gene regulation is(More)
We previously discovered (-)-DHMEQ as a selective inhibitor of NF-κB, and it was shown to suppress many cancer and inflammation models in animals. (-)-DHMEQ directly binds to NF-κB components to inhibit DNA binding, and moreover, it often inhibits nuclear translocation of NF-κB. The mechanism of inhibiting nuclear translocation has been elucidated for RelB,(More)
