The class of proteins collectively known as periplasmic immunoglobulin-like chaperones play an essential role in the assembly of a diverse set of adhesive organelles used by pathogenic strains of Gram-negative bacteria. Herein, we present a combination of genetic and structural data that sheds new light on chaperone-subunit and subunit-subunit interactions in the prototypical P pilus system, an...
In spite of the progress in the treatment of lysosomal storage diseases (LSDs), in some of these disorders the available therapies show limited efficacy and a need exists to identify novel therapeutic strategies. We studied the combination of enzyme replacement and enzyme enhancement by pharmacological chaperones in Pompe disease (PD), a metabolic myopathy caused by the deficiency of the lysoso...
To develop an ideal blood clot imaging and targeting agent, a single-chain antibody (SCA) fragment based on a fibrin-specific monoclonal antibody, MH-1, was constructed and produced via secretion from Bacillus subtilis. Through a systematic study involving a series of B. subtilis strains, insufficient intracellular and extracytoplasmic molecular chaperones and high sensitivity to wall-bound pro...
Paracoccidioides brasiliensis is a thermally dimorphic and a human pathogenic fungus. Our group has partially sequenced its transcriptome and generated a database of mycelial and yeast PbAESTs (P. brasiliensis assembled expressed sequence tags). In the present review we describe the identification of PbAESTs encoding molecular chaperones. These proteins, involved in protein folding and renatura...
Molecular chaperones (heat shock proteins) are important components of cellular networks, such as protein-protein and gene regulatory networks. Chaperones participate in the folding of immunologically important proteins, presentation of antigens and activation of the immune system. Here, we propose that chaperone-related immune dysfunction might be more general than was previously thought. Muta...
In the dense cellular environment, protein misfolding and inter-molecular protein aggregation compete with protein folding. Chaperones associate with proteins to prevent misfolding and to assist in folding to the native state. In Escherichia coli, the chaperones trigger factor, DnaK/DnaJ/GrpE, and GroEL/ES are the major chaperones responsible for insuring proper de novo protein folding. With mu...
Over 50% cancer bears TP53 mutation, the highly stabilized mutant p53 protein drives tumorigenesis and progression. Mutation of not only cause loss-of-function dominant-negative effects (DNE), but also results in abnormal stability by regulation ubiquitin-proteasome system molecular chaperones that promote through gain-of-function effects. The accumulation is mainly regulated chaperones, includ...
