We have recently described that autophagic targeting of Src maintains cancer cell viability when FAK signalling is defective. Here, we show that the Ret tyrosine kinase is also degraded by autophagy in cancer cells with altered/reduced FAK signalling, preventing its binding to FAK at integrin adhesions. Inhibition of autophagy restores Ret localization to focal adhesions. Importantly, Src kinase activity is required to target Ret to autophagosomes and enhance Ret degradation. Src is thus a general mediator of selective autophagic targeting of adhesion-linked kinases, and Ret a second FAK-binding tyrosine kinase degraded through autophagy in cancer cells under adhesion stress. Src—by controlling not only its own degradation but also that of other FAK-binding partners—allows cancer cell survival, suggesting a new therapeutic strategy.
