Università degli Studi di Napoli "Federico II"Abstract
The project focuses on differential studies of proteomes or protein complexes (complexomes) involved in the different steps of signal transduction. A major goal of the project is the development of novel experimental strategies and advanced technologies required by the proposed studies.Cell survival relies on multiple regulated metabolic processes, prompted by the ability to react to external stimuli. Cellular activity can be viewed as the integration of activation processes, stabilization of activated molecular complexes and degradation. A characterization of the bulk of proteins activated in vivo via phosphorylation (phosphoproteome) is essential for understanding regulatory mechanisms of the signalling pathways. The first aim of the proposal, besides the identification of proteins involved in a given signalling pathway, is the identification of residues recognised by kinase-phosphatase enzymatic systems in various phases of the cell cycle. The second goal of the proposal is directed to understanding the systemic response to CA2+-dependent stimulation due to formation of isopeptidic bonds catalysed by transglutaminase. The goal is the differential analysis of the proteins and amino acid residues involved (transglutamome). Conjugation to ubiquitin is an important metabolic step for termination of the signalling process; a description of the proteome involved in the ubiquitin pathway (ubiquitinome) will be the third goal of the project. Finally identification of the>>>

GENNARO MARINO, Universita' degli Studi di NAPOLI "Federico II"Research Goal
There is an essential need to improve present proteomics methodologies towards an extensive sensitivity coupled with affordable and confident quantitation.The final aim of this project is to make significant advances in differential proteomics toward this end. To face with this challenge the project is focused on differentially displayed proteomics in connection with the major events of signal transduction, a key issue in functional genomics. Since mass spectrometry and multidimensional separations are the core methods in proteomic studies, the most experienced Italian groups in biomolecular mass spectrometry and in separation methodologies will merge with an outstanding research group, specialised in low-temperature physics, who have developed a prototype of an extremely sensitive MALDI mass spectrometer. To focus on the specific biological issue of signal transduction proteomics, several research groups, all in the forefront of the international cellular and molecular biology research, will be involved in the project with the aim both to integrate their expertise and to make significant advancement in their fields by making use of the proteomics strategies and technologies made already available or to be developed.
The use of a novel mass spectrometer, equipped with a cryogenic detector, in proteomics may be considered a result per se and may pave the way to the discovery of so far unknown proteins modulating fine cellular signals. These expression products>>>
