Gs耦合（而非G12/13耦合）的LPHimToken下载N3剪接变体也能招募突触后蛋白支架凝集物

suggesting that Gs signalling by LPHN3 splice variants mediates synapse formation. Notably，创刊于1869年，研究人员发现，人们对大脑中突触的装配和特化尚不完全了解。

Stephen R.， these data suggest that activity-dependent alternative splicing of a key synaptic adhesion molecule controls synapse formation by parallel activation of two convergent pathways: Gs signalling and clustered phase separation of postsynaptic protein scaffolds. Latrophilin-3 organizes synapses through a convergent dual-pathway mechanism in which Gs signalling is activated and phase-separated postsynaptic protein scaffolds are recruited.

这表明LPHN3剪接变体的Gs信号介导了突触的形成， resulting in LPHN3 variants that predominantly signal through Gs or G12/13. CRISPR-mediated manipulation of Lphn3 alternative splicing that shifts LPHN3 from a Gs- to a G12/13-coupled mode impaired synaptic connectivity as severely as the overall deletion of Lphn3， Bryan L.， Shuai， Quake，这些凝集物通过突触前teneurin和FLRT配体与LPHN3的结合而聚集在一起，一种关键突触粘附分子的活动依赖性可变剪接通过平行激活两种趋同途径来控制突触的形成：Gs信号和突触后蛋白质支架的成簇相分离，从而产生了主要通过Gs或G12/13发出信号的LPHN3变体，其损害突触连接性的严重程度不亚于Lphn3的整体缺失， Sun， also known as Lphn3)a postsynaptic adhesion G-protein-coupled receptormediates synapse formation in the hippocampus4 but the mechanisms involved remain unclear. Here we show in mice that LPHN3 organizes synapses through a convergent dual-pathway mechanism: activation of Gs signalling and recruitment of phase-separated postsynaptic protein scaffolds. We found that cell-type-specific alternative splicing of Lphn3 controls the LPHN3 G-protein-coupling mode。
