The LINC complex forms within this structure when nesprin binds a SUN protein with its own KASH domain. Hutchinson-Gilford syndrome is caused by a farnesylated form of progerin that anchors itself to this structure. The "oily spaghetti" model describes a complex in this structure with many phenylalanine-glycine repeats. This structure's presence distinguishes closed mitosis from open mitosis. Importins and exportins bind Ran GTPase when shuttling cargo across this structure through “pore complexes.” This structure is supported by a network of intermediate filaments called the lamina that dissolves after prophase to expose the chromosomes. The endoplasmic reticulum is continuous with (10[1])the (10[1])outer face of, for 10 points, (10[1])what double lipid (10[1])bilayer that encloses a cell's genetic material? ■END■
