1549-全蛋白质组CRBN分子胶降解剂结合图谱
from 聊聊Sci
这篇研究介绍了一种名为 GluePCA 的高通量筛选平台，旨在系统性地识别分子胶降解剂（MGDs）诱导的蛋白质相互作用。研究人员利用该技术配合人工智能工具 MaSIF-mimicry，成功在全球范围内绘制了CRBN 蛋白酶的潜在作用靶点图谱。实验不仅证实了超过 200 个锌指蛋白能够与 CRBN 结合，还发现了 43 个此前未知的非典型结合物。通过深入分析结构生物学数据，团队揭示了分子胶如何通过招募“辅助锌指”来提升降解的特异性。最后，研究展示了如何利用这些新发现的结合点作为起点，开发出针对 RNF39 等难成药靶点的创新型蛋白质降解药物。该工作为扩展诱导接近药理学的覆盖范围提供了强有力的工具和理论支持。References:Galli P, Xiao S, Meng Y, et al.

Deep Dream State
Neural Nets And Pretty Patterns
Deep Dream State is a full-cast dystopian sci-fi and desire horror audio drama by Neural Nets and Pretty Patterns. As the originating work of desire horror, it locates the uncanny inside wanting itself. While conventional horror positions you against a threat, desire horror implicates you in it. The horror emerges from recognition: the realization of why characters stay, and why surrender feels like relief. Since 2017, the show has used research in dream science, surveillance studies, behavioral economics, and advertising technology to examine systems of control through immersive sound design and full-cast performance.
