physiological function

Saccharomyces cerevisiae

deletion of the rim101 gene involved in sporulation control results in upregulation of the PRB1 gene leading to higher levels of proteinase B activity. Increase in proteinase B activity results in severely compromised stability of some proteins such as Slt2p or Chs4p
