Gene Details:

Functional Descriptions:

  • A cathepsin F-like peptidase involved in barley grain protein mobilization, HvPap-1, is modulated by its own propeptide and by cystatins.
  • The expression of HvPap-1 in several barley tissues, its subcellular location in embryos, and its response in aleurone layers to GA are shown.
  • The functional role of HvPap-1 in mobilizing storage proteins, mainly hordeins, regulated either by specific inhibitors (cystatins) or by its own propeptide is also discussed.
  • These three features support the implication of HvPap-1 in storage protein mobilization during grain germination. In addition, a complex regulation exerted by the barley cystatins, which are cysteine protease inhibitors, and by its own propeptide, is also described.
