RNA stores tau reversibly in complex coacervates
Nonmembrane-bound organelles that behave like liquid droplets are widespread among eukaryotic cells. Their dysregulation appears to be a critical step in several neurodegenerative conditions. Here, we report that tau protein, the primary constituent of Alzheimer neurofibrillary tangles, can form liquid droplets and therefore has the necessary biophysical properties to undergo liquid-liquid phas...
متن کاملA major role for Tau in neuronal DNA and RNA protection in vivo under physiological and hyperthermic conditions
Nucleic acid protection is a substantial challenge for neurons, which are continuously exposed to oxidative stress in the brain. Neurons require powerful mechanisms to protect DNA and RNA integrity and ensure their functionality and longevity. Beside its well known role in microtubule dynamics, we recently discovered that Tau is also a key nuclear player in the protection of neuronal genomic DN...
متن کاملImpact of macromolecular crowding on RNA/spermine complex coacervation and oligonucleotide compartmentalization.
We report the effect of neutral macromolecular crowders poly(ethylene glycol) (PEG) (8 kDa) and Ficoll (70 kDa) on liquid-liquid phase separation in a polyuridylic acid (polyU)/spermine complex coacervate system. The addition of PEG decreased both the amount of spermine required for phase separation and the coacervation temperature (TC). We interpret these effects on phase behavior as arising d...
متن کاملEggshell-supported-Cu(II) salophen complex: An efficient and green catalyst for synthesis of propargylamines under solvent-free conditions
In this report, the synthesis, characterization, and application of the eggshell-supported-Cu(II) salophen complex, as a novel and heterogeneous catalyst, is described. The catalyst is characterized by the UV, XRD, FT-IR, and SEM techniques. The eggshell-supported-Cu(II) salophen complex is a versatile, green, inexpensive, and simple catalyst used for the multi-component reactions (MCRs) of ter...
