Homologous Superfamily

LEM/LEM-like domain superfamily (IPR011015)

Short name: LEM/LEM-like_dom_sf

Description

The LEM domain is a ~40-residue motif found in nuclear membrane-associated proteins, including lamino-associated polypeptide 2 (LAP2), emerin, MAN1, otefin and Lem-3 [PMID: 11792821]. Defects in the emerin gene are a cause of Emery-Dreifuss muscular dystrophy, an X-linked disorder characterised by early contractures, muscle wasting, weakness and cardiomyopathy. The N-terminal LEM domain in emerin mediates binding to BAF (barrier-to-autointegration factor).

All LAP2 isoforms also share an N-terminal segment composed of a LEM domain that is connected to a highly divergent LEM-like domain by a highly flexible 60-residue linker. The LEM-like globular domain has the same size and structural fold as the LEM domain, but has been shown to bind directly to DNA [PMID: 10671519, PMID: 11500367, PMID: 11435115].
