Gene Details:
- Gene ID: HORVU.MOREX.r2.5HG0414750
- Gene Symbol: HvPap-1
- Gene Name: putative cysteine proteinase precursor
- Genome: MorexV3_pseudomolecules_assembly
- Species: Hordeum vulgare
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.
