A common progeria is caused by a defect in the class V intermediate filaments on the interior of this structure, which are called (*)  lamins.
The HIV Rev response element forms a complex with the Crm1 protein that localizes to this structure. A group of proteins that form the Y-complex on this structure have consecutive repeats of phenylalanine-glycine. The Ran GTPase shuttles molecules with an NES through this structure with the help of exportin and importin. A common progeria is caused by a defect in the class V intermediate filaments on the interior of this structure, which are called (*)  lamins. This structure has small holes called porins and completely dissolves during prometaphase so that the chromosomes can bind to spindle fibers. This double membrane is continuous with the endoplasmic reticulum. For 10 points, name this envelope that surrounds the cell's genetic material.
