Shank家族蛋白(Shank1, Shank2和Shank3)是突触支架蛋白,在兴奋性谷氨酸突触的突触后密度(PSD)组织广泛的蛋白质复合物。最近的人类遗传学研究表明,SHANK家族基因(SHANK1、SHANK2和SHANK3)是特发性自闭症谱系障碍(ASD)的致病基因。小鼠Shank突变的神经生物学研究支持ASD病理生理学中突触功能障碍的一般假设。然而,SHANK家族基因产物的分子多样性,以及人类和小鼠表型的异质性,给人类SHANK突变的建模带来了挑战。在这里,我们回顾了人类ASD中SHANK突变的分子遗传学,并讨论了最近在小鼠中模拟这种突变的发现。Shank小鼠突变体突触功能障碍和相应行为的保守特征可能有助于解剖ASD的病理生理,但也突出了同一基因中不同突变引起的不同表型。
Shank family proteins (Shank1, Shank2, and Shank3) are synaptic scaffolding proteins that organize an extensive protein complex at the postsynaptic density (PSD) of excitatory glutamatergic synapses. Recent human genetic studies indicate that SHANK family genes (SHANK1, SHANK2, and SHANK3) are causative genes for idiopathic autism spectrum disorders (ASD). Neurobiological studies of Shank mutations in mice support a general hypothesis of synaptic dysfunction in the pathophysiology of ASD. However, the molecular diversity of SHANK family gene products, as well as the heterogeneity in human and mouse phenotypes, pose challenges to modeling human SHANK mutations. Here, we review the molecular genetics of SHANK mutations in human ASD and discuss recent findings where such mutations have been modeled in mice. Conserved features of synaptic dysfunction and corresponding behaviors in Shank mouse mutants may help dissect the pathophysiology of ASD, but also highlight divergent phenotypes that arise from different mutations in the same gene.
