WebRecent studies have indicated that tau, a protein involved in Alzheimer's disease and other neurodegenerative disorders, has a propensity to undergo liquid–liquid phase separation (LLPS). However, the mechanism of this process remains unknown. Here, we demonstrate that tau LLPS is largely driven by intermolecular electrostatic interactions between the … WebJan 15, 2024 · Liquid–liquid phase separation (LLPS) of proteins has recently been shown to be important for protein aggregation involved in amyotrophic lateral sclerosis, whereas tau phase separation has been linked to Alzheimer's disease. We therefore investigated the interaction of α-synuclein with tau and its consequences on tau LLPS.
WebAug 25, 2024 · Liquid-liquid phase separation (LLPS) of proteins into biomolecular condensates has emerged as a fundamental principle underpinning cellular function and malfunction.

WebMar 17, 2024 · The term “ coacervation” refers solely to the condensation of Tau with polyanionic co-factors, in the absence of crowding. In the neuronal cytoplasm, Tau encounters RNA, microtubules, and other polyanions and thus may undergo crowding- and polyanion-induced condensation at the same time. WebAug 25, 2024 · Previous studies have reported liquid–liquid phase separation of Tau, causing the formation of Tau condensates in solutions (Kanaan et al, 2024) and the cytosol of live cells (Wegmann et al, 2024). Moreover, in a cell-free system, microtubules have been shown to catalyze Tau condensation and concentrate Tau molecules in focal regions …
