Protein: E3 ubiquitin-protein ligase TRIM65 (Q8BFW4)
Organism: Mus musculus (Mouse)
Function: E3 ubiquitin ligase that plays a role in several processes including innate immnity, autophagy or inflammation. Negatively regulates miRNAs by modulating the ubiquitination and stability of TNRC6A, a protein involved in RNA- mediated gene silencing by both micro-RNAs (miRNAs) and short interfering RNAs. This ubiquitination results in the suppressed expression of miR-138-5p leading to increased autophagy (By similarity). Upon enteroviral infection, promotes 'Lys-63'-mediated ubiquitination activation of IFIH1/MDA5 leading to innate signaling cascade. Mechanistically, selectively recognizes MDA5 filaments that occur on dsRNAs (By similarity). Also plays a role in limitation of inflammation through different mechanisms. First, promotes 'Lys-48'- mediated ubiquitination of VCAM1 leading to its degradation and limitation of LPS-induced lung inflammation. In addition, negatively regulates inflammasome activation by promoting 'lys48'-linked ubiquitination of NLRP3 which is critical for the inhibition of NLRP3 inflammasome activation in resting macrophages
