'''NMR structures of the C-terminal globular domain of human lamin A/C'''<br />


==Overview==
==Overview==
Lamins are nuclear intermediate filaments that, together with, lamin-associated proteins, maintain nuclear shape and provide a structural, support for chromosomes and replicating DNA. We have determined the, solution structure of the human lamin A/C C-terminal globular domain which, contains specific mutations causing four different heritable diseases., This domain encompasses residues 430-545 and adopts an Ig-like fold of, type s. We have also characterized by NMR and circular dichroism the, structure and thermostability of three mutants, R453W and R482W/Q, corresponding to "hot spots" causing Emery-Dreifuss muscular dystrophy and, Dunnigan-type lipodystrophy, respectively. Our structure determination and, mutant analyses clearly show that the consequences of the mutations, causing muscle-specific diseases or lipodystrophy are different at the, molecular level.
