UBR4 is an E3 ligase (E3) of the N-degron pathway and is involved in
neurodevelopment, age-associated muscular atrophy and cancer progression. The location
and mechanistic classification of the E3 module within the 600 kDa protein UBR4 remains
unknown. Herein, we identify and characterize, at a biochemical and structural level, a distinct
E3 module within human UBR4 consisting of a novel “hemiRING” zinc finger, a helical-rich
UBR ...
