Multiple proteolytic systems, including the proteasome, contribute to CFTR processing

The molecular components of the quality control system that rapidly degrades abnormal membrane and secretory proteins have not been identified. The cystic fibrosis transmembrane conductance regulator (CFTR) is an integral membrane protein to which this quality control is stringently applied; approximately 75% of the wild-type precursor and 100% of the delta F508 CFTR variant found in most CF pa...

Proteolytic cleavage of elafin by 20S proteasome may contribute to inflammation in acute lung injury.

RATIONALE We hypothesise that elafin levels in acute lung injury (ALI) decrease over time due, in part, to proteolytic degradation as observed in other lung diseases. OBJECTIVES The aim of this study was to characterise temporal changes in elafin concentration in patients with ALI and to evaluate whether a decrease in elafin levels is due to elevated protease activity. METHODS Bronchoalveol...

Rad23 promotes the targeting of proteolytic substrates to the proteasome.

Rad23 contains a ubiquitin-like domain (UbL(R23)) that interacts with catalytically active proteasomes and two ubiquitin (Ub)-associated (UBA) sequences that bind Ub. The UBA domains can bind Ub in vitro, although the significance of this interaction in vivo is poorly understood. Rad23 can interfere with the assembly of multi-Ub chains in vitro, and high-level expression caused stabilization of...

Degradation of CFTR by the ubiquitin-proteasome pathway

Most cases of cystic fibrosis are caused by mutations that interfere with the biosynthetic folding of the cystic fibrosis transmembrane conductance regulator (CFTR), leading to the rapid degradation of CFTR molecules that have not matured beyond the endoplasmic reticulum (ER). The mechanism by which integral membrane proteins including CFTR are recognized and targeted for ER degradation and the...

The immunoproteasome, the 20S proteasome and the PA28αβ proteasome regulator are oxidative-stress-adaptive proteolytic complexes.

Oxidized cytoplasmic and nuclear proteins are normally degraded by the proteasome, but accumulate with age and disease. We demonstrate the importance of various forms of the proteasome during transient (reversible) adaptation (hormesis), to oxidative stress in murine embryonic fibroblasts. Adaptation was achieved by 'pre-treatment' with very low concentrations of H2O2, and tested by measuring i...
