Research Question¶
The debate highlighted that G2019S shows elevated baseline RAB10 phosphorylation, but it's unclear whether this represents true signal amplification during lysosomal swelling or just a higher activity floor. This distinction is crucial for understanding disease mechanisms and therapeutic targeting.
