Molecular mechanism of HUWE1-HAPSTR1-USP7-mediated ubiquitin chain amplification on nuclear proteins.

Rapid protein turnover is essential for cellular stress adaptation. HUWE1 (HECT, UBA, and WWE domain containing 1), a large HECT-type E3 ligase, regulates many short-lived stress-responsive proteins, yet the mechanisms underlying its substrate selectivity remain unclear. Here, we reveal that HUWE1 functions as a ubiqui...

A scalable human neuron model of Alzheimer’s disease relevant tauopathy reveals mechanisms linking Tau fibrillization to synaptic dysfunction

The development of scalable iPSC-neuron models enables tauopathy drug discovery and reconstructs progressive Tau seeding, fibrillization and synaptic dysfunction, and establishes a physiologically relevant, scalable platform for therapeutic screening that connects Tau seed uptake, site-specific phosphorylation, fibril...
