The data presented here suggest that KIF5B is implicated in several pathwaysinvolving lysosomes and that its highly expressed in all cancer cell lines tested,as compared to other N-Kinesins including KIF5A/KIF5C (Kinesin 1 family), KIF3A(Kinesin 2 family) and KIF1A (Kinesin 3 family). This evidence concerns the gene KIF5A and cancer.
