a

Colocalization of fluorescently tagged pore protein with the lesion in either wild-type or nup133ΔN mutant cells (which clusters NPCs to one side of the nucleus; Doye, Wepf and Hurt 1994).

b

Preferential localization of the lesion at the periphery of the nucleus (zone 1) by zoning analysis.

c

Induced collapsed fork by treatment with 0.2 M HU and 0.03% MMS.

d

(CAG)70 or (CAG)130 repeat tracts.

e

Mutant causes partial delocalization.

f

Concluded to be NHEJ in Therizols et al. (2006), but a significant fraction (at least 40%) had what is now accepted as a MMEJ signature.
