When D. discoideum is present in an excess of 103 to 104 fold, aggregation of D. discoideum cells appears normal, with the same kinetics as pure D. discoideum preparations, leading to aggregate formation 10 12 hours after the food was removed.
Although aggregation usually cannot be completely suppressed because of the functional and structural constraints of the native fold, aggregation is reduced substantially by placing charged residues and/or β-sheet breaking residues adjacent to aggregation-prone segments [189].
Molecular chaperones are believed to prevent undesirable folding pathways such as premature folding, aggregation and misfolding and thereby facilitate formation of biologically active protein structures [ 9].
The second screen contains small molecules that can affect the folding, aggregation state and solubility of the protein construct and also includes small molecules that specifically bind and stabilize proteins.
Heat shock proteins (HSPs) are involved in protein folding, aggregation, transport and/or stabilization by acting as a molecular chaperone, leading to inhibition of apoptosis by both caspase dependent and/or independent pathways.
These results indicate that the amicyanin signal sequence may be particularly useful for prokaryotic expression of proteins which are prone to mis-folding, aggregation or formation of inclusion bodies, all of which were circumvented in this study.
These observations led to the hypothesis that altering the normal equimolar tau isoform ratio promotes pro-assembly tau folding, aggregation, and filament formation.
Both batches of Bet v 1.0401 were extensively characterized by an array of physicochemical as well as immunological methods to compare protein primary structure, purity, quantity, folding, aggregation state, thermal stability, and antibody binding capacity.
Both production batches were analyzed by an array of physicochemical methods for primary structure, purity, quantity, folding, aggregation state, and thermal stability [15] as well as immunologically investigating antibody binding on solid surface and in solution.
Production and isolation of heterologous proteins from E. coli is often limited by insolubility, citotoxicity, uncorrect folding, aggregation in inclusion bodies and lack of secretion [ 2].
Particular attention has been directed towards identifying proteins that interact with CFTR with the goal of understanding and restoring normal CFTR proteostasis through the correction of CFTR synthesis, folding, aggregation, degradation, trafficking and stable localization.
