Analysis of motile melanosome population and fraction of reversal steps. Fraction of reversal steps was calculated in a 30-second interval.

RPE source	Percentage of motile melanosomes	Average number of reversal steps
Wild type	60.4 ± 4.3	0.9
Shaker-1	86.2 ± 3.5	1.7
Ashen	87.3 ± 5.2	2.06
Ashen+ Ad GFP-Rab27a	56.4 ± 4.1	1
Wild type + Ad GFP-shRNA5 mMyrip	94.1 ± 2.15	2.13
Wild type treated with nocodazole	18.4 ± 5.4	0
Wild type treated with cytochalasin D	72.2 ± 3.6	2.2
Dilute	54.7 ± 1.9	1.1
