LEM DOMAIN OF HUMAN INNER NUCLEAR MEMBRANE PROTEIN LAP2
Contents |
Overview
BACKGROUND: 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., RESULTS: We have determined the three-dimensional structures of the LEM, and LEM-like domains of LAP2 using nuclear magnetic resonance and, molecular modeling. Both domains adopt the same fold, mainly composed of, two large parallel alpha helices. CONCLUSIONS: The structural LEM motif is, found in human inner nuclear membrane proteins and in protein-protein, interaction domains from bacterial multienzyme complexes. This suggests, that LEM and LEM-like domains are protein-protein interaction domains. A, region conserved in all LEM domains, at the surface of helix 2, could, mediate interaction between LEM domains and a common protein partner.
