## FAQ

### What is hnRNPA2B1 and why do its droplets matter?

It is an RNA-binding protein whose low-complexity domain drives liquid–liquid phase separation to form membraneless organelles. The same self-association can misfire into solid aggregates, which is why its droplets are a focal point in neurodegeneration research.

### How do the D302V and P310L mutations change condensate behavior?

They make condensates form faster, fuse less freely, and harden into amyloid-positive cores. Fibrils emerge directly from the droplet interior rather than from bulk solution, showing the condensate itself is the aggregation intermediate.

### Can a short peptide fragment really drive aggregation of the full protein?

Yes. A conserved 25-amino-acid LCD region containing both mutation sites is sufficient to form amyloid fibrils on its own and to seed aggregation of the full LCD when added to pre-formed droplets, even though it cannot phase separate by itself.
