IkB-beta Proteome Profiler Antibody Arrays

The inhibitory IkB proteins (alpha, beta, epsilon) complex with and sequester NFkB family members in the cytoplasm, rendering these transcription factors inactive. When phosphorylated by an active IkB kinase (IKK) complex, IkB proteins are degraded by proteasomes, resulting in the release and nuclear translocation of active NFkB.
