Primary cilia create unique signalling compartments of the eukaryotic cell by orchestrating signalling molecules in a small, refined space. Defects in putative Ca2+ channels play a major role in cilia-dependent disorders, such as polycystic kidney disease. The central goal of this project is to determine basic mechanisms of Ca2+ homeostasis in cilia and how they impact the signalling environment of cilia in health and disease. To this end we are combining advanced quantitative proteomics techniques with microscopic approaches using a novel cilia Ca2+ sensor to tackle these questions from multiple angles.

初级纤毛通过在一个小而精致的空间中协调信号分子来创建真核细胞独特的信号室。假定的 Ca2+ 通道缺陷在纤毛依赖性疾病（例如多囊肾病）中起着重要作用。该项目的中心目标是确定纤毛中 Ca2+ 稳态的基本机制以及它们如何影响健康和疾病中纤毛的信号环境。为此，我们将先进的定量蛋白质组学技术与微观方法相结合，使用新型纤毛 Ca2+ 传感器从多个角度解决这些问题。
