LEM DOMAIN OF HUMAN INNER NUCLEAR MEMBRANE PROTEIN EMERIN

Contents

Overview

Like Duchenne and Becker muscular dystrophies, Emery-Dreifuss muscular, dystrophy (EDMD) is characterized by myopathic and cardiomyopathic, abnormalities. EDMD has the particularity of being linked to mutations in, nuclear proteins. The X-linked form of EDMD is caused by mutations in the, emerin gene, whereas autosomal dominant EDMD is caused by mutations in the, lamin A/C gene. Emerin colocalizes with lamin A/C in interphase cells, and, binds in vitro to lamin A/C. Recent work suggests that lamin A/C might, serve as a receptor for emerin. We have undertaken a structural analysis, of emerin, and in particular of its N-terminal domain, which is comprised, in the emerin segment critical for binding to lamin A/C. We show that, region 2-54 of emerin adopts the LEM fold. This fold was originally, described in the two N-terminal domains of another inner nuclear membrane, protein called lamina-associated protein 2 (LAP2). The existence of a, conserved solvent-exposed surface on the LEM domains of LAP2 and emerin is, discussed, as well as the nature of a possible common target.
