Abstract: 14-3-3 proteins are a family of dimeric proteins found in in every eukaryotic organism. Over 100 proteins bind to 14-3-3, including various protein kinases and phosphatases: proteins involved in cell cycle control and in transcriptional control of gene expression, metabolism, and apoptosis. 14-3-3 proteins are known in plants as regulators of the proton pump H+-ATPase. Plasma membrane H+-ATPases constitute a family of proton pumps driven by hydrolysis of ATP and are found exclusively in the plasma membrane of plants and fungi. The enzyme's C-terminus regulatory domain is an autoinhibitory domain that interacts directly with regulatory protein 14-3-3. The study carried out in this thesis has been divided in two parts: in the first one we investigated the possible role of the polyamines in modulating 14-3-3 association with the H+-ATPase. Polyamines are abundant polycationic compounds involved in many plant physiological processes such as cell division, dormancy breaking, plant morpho...
