NF2 encodes Merlin, a tumor suppressor protein that plays a crucial role in regulating cell growth and death through multiple signaling pathways. Merlin functions as a central regulator of the Hippo signaling pathway, where it activates downstream effectors to suppress the oncogenic transcriptional co-activators YAP and TAZ 12. The protein also modulates ferroptosis, a form of programmed cell death, through intercellular E-cadherin interactions that activate NF2-Hippo signaling to suppress ferroptotic cell death 23. NF2 mutations are specifically associated with the development of schwannomas, meningiomas, and ependymomas, with distinct clinical presentations based on mutational status 45. NF2-deficient tumors, particularly meningiomas with NF2 loss, show increased susceptibility to ferroptosis-inducing therapies 3, while NF2-null schwannomas and meningiomas can be effectively targeted through inhibition of YAP/TAZ-driven TEAD activity 1. The protein's involvement extends to immune microenvironment regulation, where NF2 alterations influence immunotherapy outcomes in mesothelioma 6. Merlin's multifaceted role in growth control, apoptosis regulation, and tumor suppression makes it a critical target for therapeutic intervention in NF2-associated cancers.
