RFFL

E3 ubiquitin-protein ligase RFFL (Ring Finger And FYVE Like Domain Containing E3 Ubiquitin) is a ubiquitin ligase enzyme that in humans is encoded by the RFFL gene.^[5][6] RFFL associates with endosomes.^[7] RFFL is known to affect cardiac repolarization,^[8] Cystic fibrosis transmembrane conductance regulator (CFTR) ubiquitination,^[9] and mitochondrial clearance by affecting Parkin/PRKN recruitment.^[7]
