설명

일반 설명

Chemical structure: polyether

Nigericin, a polyether ionophore, serves as a probe of ion transport across mitochondrial membranes. It catalyzes the overall electroneutral exchange of K+ for H+(1) and acts as a potassium efflux activator. It may enhance bactericidal action via inflammasome-independent mechanisms specific to NLRP3 (NOD-, LRR- and pyrin domain-containing protein 3). Nigericin is a linear molecule with rings of heterocyclic oxygen together with a hydroxyl group. In the membrane, the molecule cyclizes to form a structure like valinomycin. Nigericin forms a neutral complex while losing a proton when it binds a cation which can diffuse across the membrane as a mobile carrier. Nigericin in protonated noncomplexed form is also considered mobile.

애플리케이션

Nigericin sodium salt has been used to induce NLRP3 inflammasome activation in human macrophages. It has also been used as a bacterial toxin to trigger IL-1β secretion monocytes.
