Bacterial Inclusion Bodies Contain Amyloid-Like Structure
Protein aggregation is a process in which identical proteins self-associate into imperfectly ordered macroscopic entities. Such aggregates are generally classified as amorphous, lacking any long-range order, or highly ordered fibrils. Protein fibrils can be composed of native globular molecules, such as the hemoglobin molecules in sickle-cell fibrils, or can be reorganized beta-sheet-rich aggre...
متن کاملThe prion-like RNA-processing protein HNRPDL forms inherently toxic amyloid-like inclusion bodies in bacteria
BACKGROUND The formation of protein inclusions is connected to the onset of many human diseases. Human RNA binding proteins containing intrinsically disordered regions with an amino acid composition resembling those of yeast prion domains, like TDP-43 or FUS, are being found to aggregate in different neurodegenerative disorders. The structure of the intracellular inclusions formed by these prot...

متن کاملDistinguishing crystal-like amyloid fibrils and glass-like amorphous aggregates from their kinetics of formation.
Amyloid fibrils and amorphous aggregates are two types of aberrant aggregates associated with protein misfolding diseases. Although they differ in morphology, the two forms are often treated indiscriminately. β(2)-microglobulin (β2m), a protein responsible for dialysis-related amyloidosis, forms amyloid fibrils or amorphous aggregates depending on the NaCl concentration at pH 2.5. We compared t...
متن کاملAmyloid-like features of polyglutamine aggregates and their assembly kinetics.
The repeat length-dependent tendency of the polyglutamine sequences of certain proteins to form aggregates may underlie the cytotoxicity of these sequences in expanded CAG repeat diseases such as Huntington's disease. We report here a number of features of various polyglutamine (polyGln) aggregates and their assembly pathways that bear a resemblance to generally recognized defining features of ...
