Schemes of the three LEM domain proteins in
C. elegans showing the positions of LEM domains (black)
and transmembrane domains (dark gray). Also shown are the amino acid
sequences of the LEM domains of Ce-Lem3 (Lem3), human MAN1 (hMAN),
Ce-MAN1, human emerin (hEmerin), and Ce-emerin (Emerin). Numbering of
the amino acids is arbitrary. Black shading indicates identical
residues, gray shading indicates conserved residues, and dashes
indicate gaps introduced to optimize homology.
