Run lengths, velocities, and width of stepping angle for HM7AΔTail/LZ on different actin structures

Experiments were done on demembranated MEF-3T3 cells in the presence of 2 mMATP (see “Experimental Procedures”). Mean ± S.E. is shown.

Actin structure	Run length (λ)	Velocity	S.D. (σ) for stepping anglea
	μm	nm s−1	Degree
Stress fibers	0.41 ± 0.03	6.6 ± 0.6	61.8
	(n = 60)	(n = 60)	(n = 274)
Lamellipodia	0.59 ± 0.06	8.1 ± 0.2	47.3
	(n = 57)	(n = 57)	(n = 263)
Filopodia	0.69 ± 0.13	9.5 ± 0.4	35.4
	(n = 56)	(n = 56)	(n = 270)

^a Residuals of each stepping angle to the moving direction are calculated, and the S.D. is shown.
