突触的形成涉及细胞之间的相互作用,导致形成一种为有效信息传递而优化的结构。最近的研究表明,钙粘蛋白-连环蛋白细胞粘附复合物的成分参与了突触的形成和可塑性。在这篇综述中,我们描述了最近有趣的发现,钙粘蛋白复合物的功能机制,除了调节粘附,这是相关的理解这个复杂的突触和可塑性的作用。我们描述了这种复合物如何通过以下方式起作用:(i)招募/稳定细胞内伴侣;(ii)调节细胞内信号传导途径;(iii)调节钙粘蛋白表面水平、稳定性和营业额;(iv)稳定受体;(v)调节基因表达。这些令人兴奋的发现提供了对该复合物除了调节细胞粘附之外的新功能作用的见解。
Synapse formation involves reciprocal interactions between cells resulting in formation of a structure optimized for efficient information transfer. Recent work has implicated constituents of the cadherin–catenin cell-adhesion complex in both synapse formation and plasticity. In this review, we describe recent interesting discoveries on mechanisms of cadherin complex function, in addition to regulating adhesion, that are relevant for understanding the role of this complex in synaptogenesis and plasticity. We describe how this complex acts via (i) recruitment/stabilization of intracellular partners; (ii) regulation of intracellular signaling pathways; (iii) regulation of cadherin surface levels, stability and turnover; (iv) stabilization of receptors; and (v) regulation of gene expression. These exciting discoveries provide insights into novel functional roles of the complex beyond regulating cell adhesion.
