We report here that the guanine nucleotide exchange factor ?PIX, which modulates the activity of Rho-GTPases, is a potent bimodal regulator of EGFR trafficking. ?PIX interacts with the E3 ubiquitin ligase c-Cbl, an enzyme that attaches ubiquitin to EGFR, thereby labelling this tyrosine kinase receptor for lysosomal degradation. We show that EGF stimulation induces ?PIX::c-Cbl complex formation. Simultaneously, ?PIX and c-Cbl protein levels decrease, which depends on both ?PIX binding to c-Cbl and c-Cbl ubiquitin ligase activity. Through interaction ?PIX sequesters c-Cbl from EGFR and this results in reduced EGFR ubiquitination and decreased EGFR degradation upon EGF treatment. However, quantitatively more decisive for cellular EGFR distribution than impaired EGFR degradation is a strong stimulating effect of ?PIX on EGFR recycling to the cell surface. This function depends on the GIT binding domain of ?PIX but not on interaction with c-Cbl or ?PIX exchange activity. In summary, our data demonstrate a previously unappreciated function of ?PIX as a strong promoter of EGFR recycling. We suggest that the novel recycling regulator ?PIX and the degradation factor c-Cbl closely cooperate in the regulation of EGFR trafficking: uncomplexed ?PIX and c-Cbl mediate a positive and a negative feedback on EGFR signaling, respectively; ?PIX::c-Cbl complex formation, however, results in mutual inhibition, which may reflect a stable condition in the homeostasis of EGF-induced signal flow.
