Title	Loss-of-function of ubiquitin ligase adaptor LZTR1 triggers human disease by dysregulating RAS ubiquitination
Description	Mutations in LZTR1, a substrate adaptor for cullin 3 (CUL3) ubiquitin ligase complexes1, have been recently associated with Noonan syndrome2,3 and familial Schwannomatosis4-6. Concordantly, we found that Lztr1+/- mice showed craniofacial abnormalities, cardio defects, and premature ageing; whereas loss of LZTR1 in Schwann cells drives their dedifferentiation into proliferating, pro-myelinating cells. We screened for LZTR1 substrates by trapping LZTR1 complexes from intact mammalian cells. In parallel, we analysed changes in the ubiquitin landscape induced by LZTR1 loss of function. RAS proteins emerged as substrates of the LZTR1/CUL3 complex, which inhibits the RAS pathway by ubiquitinating RAS at K170 and triggering its dissociation from the membrane. Disease-associated LZTR1 mutations affect either the LZTR1/CUL3 complex formation, or the interaction with RAS proteins. These results position LZTR1 as a key node in the RAS pathway, loss-of-function of which leads to a human disease.
