Integral membrane proteins of the inner nuclear membrane are involved in chromatin organization and postmitotic reassembly of the nucleus. The discovery that mutations in the gene encoding emerin causes X-linked Emery-Dreifuss muscular dystrophy has enhanced interest in such proteins. A common structural domain of 50 residues, called the LEM domain, has been identified in emerin MAN1, and lamina-associated polypeptide (LAP) 2. In particular, all LAP2 isoforms share an N-terminal segment composed of such a LEM domain that is connected to a highly divergent LEM-like domain by a linker that is probably unstructured.
