Description
Sup35 protein of S. cerevisiae is the translation termination factor eRF3. The altered conformation of this protein generates the [PSI+] prion phenotype . In this state, a dominant cytoplasmically inherited protein aggregates are formed which sequester the normal function of Sup35 thereby nonsense suppressor phenotype is created . The molecular chaperon Hsp104 is necessary for the formation and maintenance of the aggregates.

- Endogenous expression in S. cerevisiae.
- Overexpression of Sup35 protein by introduction of a plasmid carrying Sup35 gene into S. cerevisiae.
Anti-Sup35 antibody was used at 1/2,000 dilution. Sup35 protein was identified at 77 kDa position (Expected molecular mass of Sup35 is 76.6 kDa) . |
