NEMO (Nuclear factor-kappa B Essential Modulator) is a protein that plays a critical role in the regulation of NF-kappa B signaling pathway, which is involved in the control of various cellular processes such as inflammation, immune response, and cell survival. Mutations in the gene encoding NEMO have been linked to a rare genetic disorder called incontinentia pigmenti, which affects the skin, hair, teeth, and nails. Research in the field of NEMO focuses on understanding its role in NF-kappa B signaling and its implications for human health, particularly in the context of inflammatory and autoimmune diseases. Additionally, studies on NEMO may also provide insights into potential therapeutic targets for these conditions.
