validate these findings, we performed qPCR for the classical YAP-target genes CTGF and CYR61 in UM cells and found significant reduction in the presence of FAKi and knockdown of FAK or GNAQ (Fig.

findings, scanning through large phosphoprotein databases (PhosphoSitePlus PTM Resource, Cell signaling technology), we found that Y26 on MOB1A/B is conserved among mammals, and that this particular residue is phosphorylated in numerous high-throughput phosphoproteomic datasets (n=161) (Fig. ('Y26', 'Var', (152, 155)) ('PTM', 'biological_process', 'GO:0043687', ('96', '99')) ('MOB1A/B', 'Gene',

recognized MOB1 only when co-transfected with FAK, which was abolished upon mutation of Y26 residue on MOB1 to Y26F (Fig. ('antibody', 'cellular_component', 'GO:0019815', ('26', '34')) ('mutation',

FAKi in UM cells (Fig. ('knockdown', 'Var', (21, 30)) ('growth inhibition', 'MPA', (65, 82)) ('LATS1/2', 'Gene', '9113;26524', (13, 20)) ('LATS1/2', 'Gene', (13, 20)) 36296 30773340 We observed that

We found that FAKi reduces both UM tumor size and cell proliferation in two different UM tumor models, the latter clearly visible by Ki67 staining that was nearly absent in VS-4718 treated mice (Fig.

type specifically driven by few activating (Galphaq) mutations may serve as a good testbed for studying such an approach, harnessing a novel SL-based integrated bioinformatics analysis to uncover novel oncogenic signaling mechanisms controlled by Galphaq and target them.
