To identify regulatory responses that could give clues as to the cause(s) of the growth arrest observed in E. coli cells expressing mutant Hsp60-(p.Val98Ile) and Hsp10 versus cells expressing wild type Hsp60 and Hsp10, we performed microarray analyses. We reasoned that the decreased chaperonin activ...

The goal of this study was to identify yeast mutants with arsenite hypersensitivity. Keywords: dose response Matched pools of yeast knockout (YKO) mutants were grown in paired growth media lacking or containing arsenite at various concentrations. The relative abundances of the YKO mutants were profi...

Treatment of rheumatoid arthritis patients with chaperonin 10
Dynamics of chaperonin function in live human cells
The GroEL/GroES chaperonin mediates protein folding in bacteria in an ATP-dependent process. Studies in vitro show that the GroEL double-ring and the lid-shaped GroES transiently encapsulate unfolded protein for folding unimpaired by aggregation. To clarify critical aspects of this mechanism, we use...

Trial described in Lancet. 2006 Sep 2;368(9538):855-63. Rheumatoid arthritis patients were treated with chaperonin 10, with a dose of 10 mg rCpn10 i.v. twice weekly for 56 days. Blood samples were collected before and after treatment. Microarray analysis described in Hirata et al., Early pregnancy f...

The mitochondrial matrix is unique in that it must integrate folding and assembly of proteins derived from nuclear and mitochondrial genomes. In C. elegans, the mitochondrial unfolded protein response (UPRmt) senses matrix protein misfolding and induces a program of nuclear gene expression, includin...

TFIID is a cornerstone of eukaryotic gene regulation. Distinct TFIID complexes with unique subunit composition exist and several TFIID subunits are shared with other complexes, conveying intricate cellular decision making to control subunit allocation and functional assembly of this essential transc...
