Recent technological innovations have driven research in proteomics from single protein characterization to global approaches, aiming at achieving a comprehensive qualitative and quantitative description of complex molecular mechanisms. To achieve this task we are interested in developing and applying new technologies in the fields of mass spectrometry and proteomics. We choose mass spectrometry as the principal analytical tool as this technique is, up to now, the most sensitive and specific tool for protein microanalysis. Our group is mainly interested in the development and application of sensitive and specific methods for protein identification and microcharacterization. In particular, we are developing novel approaches that can be applied to proteome analysis of cells under physiological and pathological states.

Our laboratory has state of the art equipment for protein microanalysis and identification, including a MALDI-TOF, a Nano electrospray Q-TOF and a new LTQ-Orbitrap mass spectrometer. Other analytical tools that we use are chromatography and 2D electrophoresis.
Current research projects focus on:
"" Protein quantification (SILAC and label free)
"" Characterization of post-translationally modified proteins, including phosphoproteins, acetylated and S-nitrosylated proteins
"" Investigation of macromolecular complexes
"" Identification of proteins isolated from different sources
"" Determination and sequencing of the primary structure of proteins
"" protein-protein interactions

Project Title:
Dissecting the involment of Sp140 in leukocytes and in chronic lymphocytic leukemia (CLL)
Sp140, a leukocyte-specific protein member of the Sp100 family, localizes to promyelocytic leukemia nuclear bodies1. Sp140 is expressed in mature B cells and plasma cell lines; it plays a role in immune response to HIV-1, is an autoantigen in primary biliary cirrhosis and most importantly, polymorphisms in the gene were associated with risk of chronic lymphocytic leukemia (CLL), the most common adult leukemia in the western world2. Despite its involvement in human pathologies its physiological role and the molecular mechanism dictating its function are still unknown. Sp140 contains a tandem PHD-Bromo-domain which is known to work as epigenetic reader of histone tails recruiting transcription factors and nucleosome-associated complexes to chromatin, and as E3 ligase in intramolecular sumoylation reactions. We have recently found that Sp140 can indeed undergo sumoylation.The main goal of this project is to gain insights into the structure function-relationship of SP140 as a basis to clarify its molecular role in the pathogenesis of human malignancies and in particular of CLL. In particular, in order to understand Sp140 function, we will identify Sp140-associated proteins through a proteomic approach3 taking advantage of a large collection of CLL patient samples available at our institution, we will investigate how sumoylation may affect its function and we will characterization Sp140 as epigenetic reader in quantitative GST-Pull down.
