[Term] id: PR:000035980 name: plant U-box E3 ubiquitin ligase def: "A protein that contains a U-box domain (Pfam:PF04564) and Arm repeats (Pfam:PF00514). U-box protein is one type of E3 ubiquitin-protein ligase. E3 ubiquitin ligase plays an important role in the ubiquitin-proteasome pathway, since it recognizes target proteins for ubiquitination."
