TABLE 2:

Parameters of MT-based movement of pigment granules during pigment aggregation in melanophores expressing EGFP-XMAP4 or EGFP.

Movement parameter	EGFP-XMAP4–expressing cells	EGFP-expressing cells
Velocity of minus-end runs (nm/s)	401.5 ± 7.5	386.6 ± 8.5
Length of minus-end runs (nm)	117.1 ± 4.5*	161.9 ± 8.6*
Velocity of plus-end runs (nm/s)	355.5 ± 9.2	337.9 ± 10.1
Length of plus-end runs (nm)	36.8 ± 0.7*	39.5 ± 1.2*
Duration of pauses (s)	0.69 ± 0.03	0.66 ± 0.03
Number of analyzed pigment granules	121	80

Values are marked with an asterisk if the difference of the mean parameter value between EGFP-XMAP4– and EGFP-expressing cells is significant at the 0.05 level, according to a one-way analysis of variance test.
