The NF2-encoded protein Merlin is closely related to the Ezrin-Radixin-Moesin family of membrane/cytoskeleton linker proteins, and has been demonstrated to suppress tumor growth by inhibiting extracellular signal-regulated kinase (ERK) and Rac1 activation.
The gene for NF2, a syndrome typically associated with vestibular schwannomas and meningiomas, is homologous with a family of genes whose members appear to play an important role in bridging the cell membrane with the intracellular cytoskeleton, including moesin, ezrin, radixin, and protein 4.1.
