On the contrary, overexpression of either Eg5/WT (which might therefore still be in vivo phosphorylated) or Eg5/S1033E did not modify the mitotic phenotypes resulting from XPD/R683W [Fig. 7A (images A.9 to A.12 and A.17 to A.20); Fig. 7, B and C (bars 3 and 5)]. Here, KIF11 is linked to xeroderma pigmentosum group D.
