p100 Inhibitors

p100, also known as NFKB2, is a protein that plays a crucial role in the NF-κB (nuclear factor kappa-light-chain-enhancer of activated B cells) signaling pathway. The NF-κB pathway is central to various cellular processes, including inflammation, immunity, and cell survival. The p100 protein serves as both a precursor for the p52 protein and as an inhibitor in the non-canonical NF-κB pathway. In its full-length form, p100 associates with the RelB protein, forming an inactive complex in the cytoplasm. Upon receiving specific signals, p100 undergoes proteasomal processing to generate the p52 fragment. This processing event releases the active RelB/p52 dimer, which then translocates to the nucleus to modulate the transcription of target genes. Given the pivotal role of p100 in regulating NF-κB signaling, its activity must be tightly controlled to ensure proper cellular responses.

p100 (NFKB2) inhibitors are a class of chemical compounds designed to target and modulate the activity or processing of the p100 protein. These inhibitors might function by preventing the proteasomal processing of p100, thereby blocking the generation of the active p52 fragment and the subsequent activation of NF-κB signaling. Others could interfere with the interactions between p100 and other proteins in the pathway, such as RelB, disrupting the formation of functional complexes. Some inhibitors might also act by modulating the post-translational modifications of p100, influencing its stability, processing, or interaction with partner proteins.
