NF2 gene

NF2 (NF2, Moesin-Ezrin-Radixin Like (MERLIN) Tumor Suppressor) is a protein-coding gene located on chromosome 22q12.2.

This gene encodes a protein similar to some members of the ERM family (ezrin, radixin, moesin), a family of proteins that link components of the cytoskeleton to proteins in the cell membrane (Pećina-Šlaus N 2013). The encoded protein has been shown to interact with cell surface proteins, proteins involved in cytoskeleton dynamics, and proteins regulating ion transport.

Mutations in this gene result in an insufficient gene product and are associated with neurofibromatosis type II, which is characterized by tumors of the nervous system and skin and eye abnormalities.

Likely regulator of the Hippo/SWH (Sav/Wts/Hpo) pathway, a signaling pathway that plays a central role in tumor suppression by limiting proliferation and promoting apoptosis.

May act as a membrane stabilizing protein.

May inhibit PI3 kinase by binding to AGAP2 and impairing its stimulatory activity.

Suppresses cell proliferation and tumorigenesis by inhibiting the CUL4A-RBX1-DDB1-VprBP/DCAF1 E3 ubiquitin-protein ligase complex.
