Kinesin-1 and kinesin-3 rigor mutants differentially associate with MAP4 and MAP7D1 (a-b) Confocal images of BS-C-1 cells transiently expressing GFP-tagged (a) KIF5B-R (green) or (b) KIF1A-R (green), immunostained for endogenous MAP4 (magenta). (c) Bar plot of Mander’s colocalization quantification shows significantly higher colocalization of MAP4 with KIF1A-R ( n = 8 cells) than KIF5B-R ( n = 9 cells). (d-e) Confocal images of cells expressing GFP-tagged (d) KIF1A-R or (e) KIF5B-R (green), immunostained for endogenous MAP7D1 (magenta). (f) Bar plot of Mander’s colocalization quantification reveals significantly higher colocalization of MAP7D1 with KIF5B-R ( n = 10 cells) than KIF1A-R ( n = 9 cells). (g–h) Co-expression of KIF5B-R (green) with (g) MAP4-FL or (h) MAP4-MTBD (magenta), Line intensity profiles show MAP4-FL is excluded from KIF5B-R-decorated microtubules, while MAP4-MTBD exhibits extensive colocalization. (i) Model illustrating the preferential association of KIFB-R and KIF1A-R with MAP7D1 and MAP4, respectively. Bars represent the mean; whiskers indicate standard deviation from three independent experiments. Statistical significance was assessed using the Mann–Whitney U test (****p < 0.0001). Scale bars: 10 μm.
