The Ubiquitin-Proteasome Proteolytic Pathway: Destruction for the Sake of Construction

TL;DR: It is clear now that degradation of cellular proteins is a highly complex, temporally controlled, and tightly regulated process that plays major roles in a variety of basic pathways during cell life and death as well as in health and disease.
Journal ArticleDOI

A subcomplex of the proteasome regulatory particle required for ubiquitin-conjugate degradation and related to the COP9-signalosome and eIF3.

TL;DR: The lid subunits share sequence motifs with components of the COP9/signalosome complex and eIF3, suggesting that these functionally diverse particles have a common evolutionary ancestry.
Journal ArticleDOI

A gated channel into the proteasome core particle.

TL;DR: Crystallographic analysis showed that deletion of the tail of the α3-subunit opens a channel into the proteolytically active interior chamber of the CP, thus derepressing peptide hydrolysis.
Journal ArticleDOI

The Regulatory Particle of the Saccharomyces cerevisiae Proteasome

TL;DR: Overall, regulatory particles from yeasts and mammals are remarkably similar, suggesting that the specific mechanistic features of the proteasome have been closely conserved over the course of evolution.
Journal ArticleDOI

The base of the proteasome regulatory particle exhibits chaperone-like activity.

TL;DR: A model in which ubiquitin–protein conjugates are initially tethered to the proteasome by specific recognition of their ubiquit in chains is suggested; this step is followed by a nonspecific interaction between the base and the target protein, which promotes substrate unfolding and translocation.
