A Role For Δ-Catenin In Synaptic Regulation, Li Yuan

Theses & Dissertations

The cadherin-catenin complex regulates cell-cell adhesion and signal transduction in epithelial cells. It is becoming increasingly evident that components of the complex regulate various aspects of neuronal architecture and function. δ-catenin is a cytosolic component of the cadherin-catenin complex and is predominantly expressed in the central nervous system. Loss of CTNND2, which encodes δ-catenin, is associated with intellectual disability and mutations in CTNND2 have been identified in autism, suggesting that δ-catenin is a critical component of the molecular machinery underlying neural circuit function. We have previously demonstrated that δ-catenin regulates multiple aspects of synaptic and dendritic development, including dendritic …
