  • Title: HTRA proteases: regulated proteolysis in protein quality control.
    Author: Clausen T, Kaiser M, Huber R, Ehrmann M.
    Journal: Nat Rev Mol Cell Biol; 2011 Mar; 12(3):152-62. PubMed ID: 21326199.
    Abstract:
    Controlled proteolysis underlies a vast diversity of protective and regulatory processes that are of key importance to cell fate. The unique molecular architecture of the widely conserved high temperature requirement A (HTRA) proteases has evolved to mediate critical aspects of ATP-independent protein quality control. The simple combination of a classic Ser protease domain and a carboxy-terminal peptide-binding domain produces cellular factors of remarkable structural and functional plasticity that allow cells to rapidly respond to the presence of misfolded or mislocalized polypeptides.
