Primary sequence independence for prion formation.

Many proteins can adopt self-propagating beta-sheet-rich structures, termed amyloid fibrils. The [URE3] and [PSI+] prions of Saccharomyces cerevisiae are infectious amyloid forms of the proteins Ure2p and Sup35p, respectively. Ure2p forms prions primarily as a result of its sequence composition, as versions of Ure2p with the prion domain amino acids shuffled are still able to form prions. Here ...

A Mathematical Model for Cell Formation in CMS Using Sequence Data

Cell formation problem in Cellular Manufacturing System (CMS) design has derived the attention of researchers for more than three decades. However, use of sequence data for cell formation has been the least investigated area. Sequence data provides valuable information about the flow patterns of various jobs in a manufacturing system. This paper presents a new mathematical model to solve a cell...

Amyloids go genomic: insights regarding the sequence determinants of prion formation from genome-wide studies.

Protein misfolding is the primary cause of several systemic and neurodegenerative diseases and a major challenge in the development of protein-based therapeutics, Figure 1 top. In misfolding diseases such as cystic fibrosis and a1-antitrypsin deficiency, degradation and/or mistrafficking of specific proteins causes loss of protein function. A second class of misfolding disease includes systemic...

A promiscuous prion: efficient induction of [URE3] prion formation by heterologous prion domains.

The [URE3] and [PSI(+)] prions are the infections amyloid forms of the Saccharomyces cerevisiae proteins Ure2p and Sup35p, respectively. Randomizing the order of the amino acids in the Ure2 and Sup35 prion domains while retaining amino acid composition does not block prion formation, indicating that amino acid composition, not primary sequence, is the predominant feature driving [URE3] and [PSI...
