%A Gurmeet Kaur %A Srikrishna Subramanian %O Open Access %J Biology direct %T The UBR-box and its relationship to binuclear RING-like treble clef zinc fingers. %X The N-end rule pathway is a part of the ubiquitin-dependent proteolytic system wherein N-recognin proteins recognize the amino terminal degradation signals (N-degrons) of the substrate. The type 1 N-degron recognizing UBR-box domain of the eukaryotic Arg/N-end rule pathway is known to possess a novel three-zinc-stabilized heart-shaped fold. %K Binuclear treble clefs; zinc fingers; B-box; ZZ domain; N-end rule; novel fold; U-box %P 36 %V 10 %D 2015 %I BioMed Central %L open1764
