PROBLEM:  Virus infection does not appear to alter the amount of RelA ( p65 ) or NFKB1 ( p50 ) but rather affects the capacity of I kappa B alpha to sequester RelA ( p65 ) , therefore leading to constitutive levels of RelA DNA binding activity and to increased levels of NF - kappa B - dependent gene activity .

SOLUTION:
I kappa B
