Structure of Lamin A/C Globular Domain
Overview
The nuclear lamins form a two-dimensional matrix that provides integrity, to the cell nucleus and participates in nuclear activities. Mutations in, the region of human LMNA encoding the carboxyl-terminal tail Lamin A/C are, associated with forms of muscular dystrophy and familial partial, lipodystrophy (FPLD). To help discriminate tissue-specific phenotypes, we, have solved at 1.4-A resolution the three-dimensional crystal structure of, the lamin A/C globular tail. The domain adopts a novel, all beta, immunoglobulin-like fold. FPLD-associated mutations cluster within a small, surface, whereas muscular dystrophy-associated mutations are distributed, throughout the protein core and on its surface. These findings distinguish, myopathy- and lipodystrophy-associated mutations and provide a structural, framework for further testing hypotheses concerning lamin function.
