Figure 1. Interactions of SUN proteins and nesprins.
Depiction of SUN proteins and nesprins whose interactions through evolutionarily conserved SUN and KASH domains provide macromolecular scaffolds that span the NE and mediate physical interactions between cytoplasmic and nucleoplasmic components (see the text for more details). Blue ovals are spectrin repeats; red ovals are actin-binding domains. PNS, perinuclear space.
