Table 2. 2G4-GFP turns over on microtubules at a rate similar to MAPs.

Protein	Half time of fluorescence recovery on microtubules	Reference
2G4-GFP	4.5 ± 4.3 s	this study
GFP-tau	6.8 ± 4 s	this study
GFP-tau	2.3 ± 0.4 s	[33]
Ensconsin	4.3 s	[37]
EB1-GFP	3.6 - 12 s	[38]
CLIP-170	< 1 s	[39]

Fibroblast data is shown for GFP-tau [33]. Ensconsin turnover was measured by expression of its microtubule-binding domain fused to 5 GFPs [37]. EB1-GFP turnover on microtubule ends was measured in both mitotic and interphase Xenopus egg extracts [38]. Half times of recovery are given as mean ± SD, or as described in the publications cited.
