An alternative to the classical view of the fate of the membranous portion of the nuclear envelope is the absorption of the membranes of the nuclear envelope into the membranes of the endoplasmic reticulum (ER). This alternative view proposes that the nuclear envelope does not fragment into small vesicles, but rather the membranes of the nuclear envelope are absorbed into the membranes of the ER. This is supported by studies showing that the ER and nuclear envelope are continuous structures, and that certain proteins and lipids found in the nuclear envelope are also present in the ER.
