From the Neurofibromatosis type 2 (NF2) is a dominantly
inherited disease associated with the central nervous system. The NF2
gene product merlin is a tumor suppressor, and its mutation or
inactivation causes this disease. We report here the crystal structure
of the merlin FERM domain containing a 22-residue The atomic coordinates and the structure factors (code 1ISN) have been deposited in the Protein Data Bank, Research Collaboratory for Structural Bioinformatics, Rutgers University, New Brunswick, NJ (http://www.rcsb.org/).

-helical segment. The structure reveals that the merlin FERM domain consists of three
subdomains displaying notable features of the electrostatic surface
potentials, although the overall surface potentials similar to those of
ezrin/radixin/moesin (ERM) proteins indicate electrostatic membrane
association. The structure also is consistent with inactivation mechanisms caused by the pathogenic mutations associated with NF2.
