Eukaryotic cells are distinguished by the presence of membrane-bound compartments called organelles. This project will use structural biology to determine how essential proteins called sorting nexins (SNXs) regulate membrane interactions required for lipid droplet formation. These interactions are essential for life, controlling protein and lipid homeostasis needed for cell survival. The major outcome of this proposal will be a fundamental understanding of how SNXs control this process, and the work will significantly strengthen our international collaboration in this emerging area. The knowledge has potential future translation in the treatment of neurodegenerative disorders where dysregulation of these proteins is known to cause disease.

真核细胞通过称为细胞器的膜结合室的存在来区分。该项目将使用结构生物学来确定必需蛋白如何称为排序Nexins（SNX）调节脂质液滴形成所需的膜相互作用。这些相互作用对生命至关重要，控制细胞存活所需的蛋白质和脂质稳态。该提案的主要结果将是对SNX如何控制这一过程的基本理解，这项工作将大大加强我们在这个新兴领域的国际合作。知识在治疗神经退行性疾病的治疗中具有潜在的未来翻译，其中这些蛋白质的失调会引起疾病。
