TRIM31

E3 ubiquitin-protein ligase that acts as a regulator of antiviral immune response and inflammation by mediating ubiquitination of substrates. Acts as a regulator of innate immune defense against viruses by mediating 'Lys-63'-linked ubiquitination of MAVS, promoting MAVS polymerization and formation of three-stranded helical filaments on mitochondria. Acts as a negative regulator of the NLRP3 inflammasome by catalyzing 'Lys-48'-linked ubiquitination of NLRP3, leading to its degradation. Regulator of Src-induced anchorage independent cell growth (By similarity)..
