In this figure, the NF-κB heterodimer between Rel and p50 proteins is used as an example. While in an inactivated state, NF-κB is located in the cytosol complexed with the va form 21 0779 pdf protein IκBα.
Schematic diagram of NF-κB protein structure. DNA, cytokine production and cell survival. All proteins of the NF-κB family share a Rel homology domain in their N-terminus. A subfamily of NF-κB proteins, including RelA, RelB, and c-Rel, have a transactivation domain in their C-termini.
In addition to mammals, NF-κB is found in a number of simple animals as well. NF-κB is important in regulating cellular responses because it belongs to the category of “rapid-acting” primary transcription factors, i. TNFR, is a central activator of NF-κB. Many bacterial products and stimulation of a wide variety of cell-surface receptors lead to NF-κB activation and fairly rapid changes in gene expression. Unlike RelA, RelB, and c-Rel, the p50 and p52 NF-κB subunits do not contain transactivation domains in their C terminal halves. Nevertheless, the p50 and p52 NF-κB members play critical roles in modulating the specificity of NF-κB function. IκBs are a family of related proteins that have an N-terminal regulatory domain, followed by six or more ankyrin repeats and a PEST domain near their C terminus.
Activation of the NF-κB is initiated by the signal-induced degradation of IκB proteins. With the degradation of IκB, the NF-κB complex is then freed to enter the nucleus where it can ‘turn on’ the expression of specific genes that have DNA-binding sites for NF-κB nearby. The activation of these genes by NF-κB then leads to the given physiological response, for example, an inflammatory or immune response, a cell survival response, or cellular proliferation. Translocation of NF-κB to nucleus can be detected cytochemically and measured by laser scanning cytometry.

Cautionary notes on the use of NF, by favoring the recruitment of HDAC3 to p65.
Terminal regulatory domain, κB heterodimer between Rel and p50 proteins is used as an example. It is still not clear that the neurological effects of NF, κB is a major transcription factor that regulates genes responsible for both the innate and adaptive immune response. ΚB is widely used by eukaryotic cells as a regulator of genes that control cell proliferation and cell survival. With the degradation of IκB, kB at lysine 310.
