G2019S has two separable effects: (1) increases catalytic efficiency at baseline (higher floor), AND (2) increases LRRK2 membrane affinity upon lysosomal stress, amplifying volume-sensing signals. These may be pharmacologically separable. Membrane-association mutants could distinguish these mechanisms.
G2019S basal RAB10 phosphorylation elevation may be secondary; true pathogenic driver is amplified stress-response signaling. Partial LRRK2 inhibition sufficient to normalize stress-induced spikes while preserving necessary baseline functions. LRRK2 knockout mice viability supports non-essential baseline hypothesis. Age-dependent neurodegeneration in knock-in mice suggests stress-dependent pathology rather than chronic baseline elevation.
