We observed that mCherry-TRIM1 recruited GFP-LRRK2 to microtubules in all cell lines examined, including human lung carcinoma (A549) cells (Fig. S1 a), human neuroblastoma (SK-N-SH) cells (Fig. S1 b), and human embryonic kidney (HEK-293T) cells (Fig. S1 c), as well as human breast carcinoma (MCF7), and human (SH-SY5Y) and mouse (N2a) neuroblastoma cells (not depicted). The gene discussed is LRRK2; the disease is lung carcinoma.
