Plectin acts as an intermediary linker connecting the intermediate filaments while a motor protein (e.g: kinesin) is generally involved in linking microtubules. INM- Inner nuclear membrane; ONM- Outer nuclear membrane; LBR- Lamin B receptor. Together these provide the outward pull that maintains the nucleus in a stretched state.

While all of these alterations of lamins perturb nuclear morphology, each has a different effect on lamin-based nuclear mechanics. Lamin A mutant progerin increases nuclear stiffness, while lamin A depletion decreases stiffness, and lamin B depletion leads to either no change or increased rigidity, depending on lamin A content [ 5 , 13 , 41 , 66 ].
