Several NF2-patient-derived Merlin mutations disrupt its binding to AMOTL1 and its regulation by the AMOTL1-NEDD4L apparatus. Lysine (K) 396 is the major ubiquitin conjugation residue. Disruption of Merlin ubiquitination by the K396R mutation or NEDD4L depletion diminishes its binding to Lats1 and inhibits Lats1 activation. These effects are also accompanied by loss of Merlin's anti-mitogenic and tumor suppressive properties.
