Analysis of the Role of Snapin in the Regulation of SNARE Complex Assembly. The aims of the proposed studies are to investigate the role played by a protein, snapin in the trafficking of membranes and cargo proteins between different compartments inside mammalian cells. Membrane trafficking is a fundamental cellular process that requires a family of related molecules termed SNARES. We have recently discovered that snapin interacts with certain members of the SNARE family, implying a critical role in membrane trafficking. The proposed studies will provide important new insights into the molecular mechanisms underlying the function of both snapin and SNAREs, and membrane trafficking in general.
