G2019S specifically hyperactivates LRRK2 when recruited to swelling lysosomes via RAB29, creating pathogenic positive feedback where membrane stress increases RAB10 phosphorylation more than wild-type. Key experimental prediction: rise kinetics (slope) should differ between G2019S and WT, not merely baseline offset. RAB29 pathogenic mutations (PARK23) confirm disease relevance of this axis.
