Description
The glutamine- and asparagine-rich protein, Rnq1, is a putative yeast prion. Rnq1 protein with yet unknown function, can exists in either noninfectious soluble monomer form, [pin-], or the insoluble aggregated amyloid-like form called [PIN+]. The insoluble state is dominant and transmitted between cells through the cytoplasm (1). Rnq1 protein is necessary for the de novo induction of another prion, [PSI+] (2). The molecular chaperone Hsp104 is necessary for the aggregate formation of polyglutamine and for the maintenance of prion phenotype. The pre-existing aggregates are required for the chaperon-dependent establishment of the epigenetic trait in yeast prions (3).

PMID: 15298677
Cells were harvested after 24 h of galactose induction. Extracts were centrifuged and soluble (S) and pelleted (P) fractions were assayed by Western blotting using this antibody. Rnq1 protein was detected in pelleted fraction (ref. 3). |
