Protein: NLR family pyrin domain-containing protein 2B (Pyrin domain-containing protein 2-like protein POP4) (Pyrin-only protein 4) (P0DMW2)
Organism: Homo sapiens (Human)
Function: May function as a negative regulator of NF-kappa-B by preventing RELA/p65 phosphorylation at 'Ser-536', thereby inhibiting its transcriptional activity. Through NF-kappa-B regulation may control cytokine release upon Toll-like receptors activation and therefore play a role in modulation of innate immunity. May also play a role in cell cycle progression and apoptotic process.
