Human emerin is an inner nuclear membrane protein involved in the response of the nucleus to mechanical stress. It contributes to the physical connection between the cytoskeleton and the nucleoskeleton. It is also involved in chromatin organization. Its N-terminal region is nucleoplasmic and comprises a globular LEM domain from residue 1 to residue 43. The three-dimensional structure of this LEM domain in complex with the chromatin BAF protein was solved from NMR data. Apart from the LEM domain, the nucleoplasmic region of emerin, from residue 44 to residue 221, is predicted to be intrinsically disordered. Mutations in this region impair binding to several emerin partners as lamin A, actin or HDAC3. However the... More
