Covalent regulation of NLRP3 activation by phosphate groups: the identified phosphorylation sites on the NLRP3 protein that regulate its activity and the enzymes which are responsible for catalyzing the phosphorylation or dephosphorylation events. These enzymes may serve as potential targets to decrease the activity of the NLRP3 inflammasome in autoinflammatory and neuroinflammatory conditions.
