本综述涵盖了 Neuroligin 亚型的动态调节,重点关注翻译后事件,包括磷酸化、糖基化和活性依赖性切割。关于磷酸化如何赋予亚型特异性调节水平以影响各种蛋白质相互作用的文献越来越多。此外,最近的研究描述了神经连接蛋白的活性依赖性蛋白水解裂解,揭示了神经连接蛋白的更广泛作用而不仅仅是突触“粘合剂”。有趣的新研究表明神经胶质素的裂解细胞外片段可促进神经胶质瘤。这些关于由神经胶质素裂解产物介导的细胞信号传导的报告表明神经胶质素在神经胶质信号传导中具有新颖且重要的作用。
This review covers the dynamic regulation of neuroligin isoforms, focusing on posttranslational events including phosphorylation, glycosylation and activity-dependent cleavage. There is a growing literature on how phosphorylation confers an isoform-specific level of modulation affecting a variety of protein interactions. In addition, recent studies describe activity-dependent proteolytic cleavage of neuroligins, revealing a broader role for neuroligins than just synaptic ‘glue’. Interesting new research implicates the cleaved extracellular fragments of neuroligins in promoting glioma. These reports on cell signaling mediated by the cleavage products of neuroligins suggest novel and important roles for neuroligins in neuro-glial signaling.
