Abstract

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 [PubMed11792821]. 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).

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 3 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.


Browse and view proteins in genomes which have different domain combinations including a LEM domain domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 3 hidden Markov models representing the LEM domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
