Description

Selective proteolysis is essential for the modulation of key cellular processes such as cell cycle progression.However, unlike other post-translational events, proteolysis is irreversible and therefore must occur in unidirectional cellular pathways.In eukaryotes, proteolysis is mediated primarily by the ubiquitin pathway.This pathway designates proteins for degradation by the proteasome, a multicatalytic protease complex.The ubiquitin pathway is a multistep system that tags proteins for degradation via the attachment of ubiquitin molecules to the target.This attachment is mediated by the ubiquitin activating/conjugating enzymes E1, E2, E3, and BRUCE.BRUCE (BIR Repeat containing Ubiquitin-Conjugating Enzyme) is a novel enzyme that associates with the Golgi and the vesicular system.It contains a UBC (ubiquitin conjugating enzyme) domain, which is essential for catalysis, and a BIR (baculovirus inhibitor of apoptosis repeat) motif.BIR motifs are also found within inhibitor of apoptosis proteins (IAP) and are critical for anti-apoptotic activity.Therefore, BRUCE may function to both mediate ubiquitin-dependent proteolysis and contribute to anti-apoptotic cellular pathways.
