Similarity}. Note=Colocalized with BANF1 at the central region of the assembling nuclear rim, near spindle- attachment sites. The accumulation of different intermediates of prelamin-A/C (non-farnesylated or carboxymethylated farnesylated prelamin-A/C) in fibroblasts modify its localization in the nucleus (By similarity). {By

The nuclear envelope is a membrane system which surrounds the nucleoplasm of eukaryotic cells. It is composed of the nuclear lamina, nuclear pore complexes and two nuclear membranes. The space between the two membranes is called the nuclear intermembrane space.
The inner membrane of the nucleus is the membrane which separates the nuclear matrix from the intermembrane space. In mammals, the inner nuclear membrane is associated with heterochromatin and the nuclear lamina.
The membrane surrounding the nucleus. This term is used when it is not known if the protein is found in or associated with the inner or outer nuclear membrane.
The outer membrane of the nucleus is the membrane facing the cytoplasm. In mammals, the outer nuclear membrane is continuous in many places with the rough endoplasmic reticulum and is dotted with ribosomes.
Stabilizes and promotes the formation of a nuclear actin cortical network. Stimulates actin polymerization in vitro by binding and stabilizing the pointed end of growing filaments. Inhibits beta- catenin activity by preventing its accumulation in the nucleus. Acts by influencing the nuclear accumulation of beta-catenin through a CRM1- dependent export pathway. Links centrosomes to the nuclear envelope via a microtubule association. Required for proper localization of non- farnesylated prelamin-A/C. Together with NEMP1, contributes to nuclear envelope stiffness in germ cells. {By
