Cancer cells adopt various modes of migration during metastasis. How the ubiquitination machinery contributes to cancer cell motility remains underexplored. Here, we report that tripartite motif (TRIM) 59 is frequently up-regulated in metastatic breast cancer, which is correlated with advanced clinical stages and reduced survival among breast cancer patients. TRIM59 knockdown (KD) promoted apoptosis and inhibited tumor growth, while TRIM59 overexpression led to the opposite effects. Importantly, we uncovered TRIM59 as a key regulator of cell contractility and adhesion to control the plasticity of metastatic tumor cells. At the molecular level, we identified programmed cell death protein 10 (PDCD10) as a target of TRIM59. TRIM59 stabilized PDCD10 by suppressing RING finger and transmembrane domain-containing protein 1 (RNFT1)-induced lysine 63 (K63) ubiquitination and subsequent phosphotyrosine-independent ligand for the Lck SH2 domain of 62 kDa (p62)-selective autophagic degradation. TRIM59 promoted PDCD10-mediated suppression of Ras homolog family member A (RhoA)-Rho-associated coiled-coil kinase (ROCK) 1 signaling to control the transition between amoeboid and mesenchymal invasiveness. PDCD10 overexpression or administration of a ROCK inhibitor reversed TRIM59 loss-induced contractile phenotypes, thereby accelerating cell migration, invasion, and tumor formation. These findings establish the rationale for targeting deregulated TRIM59/PDCD10 to treat breast cancer.

Receptor-driven selective macroautophagy/autophagy delivers ubiquitinated targets for autophagosomal clearance to maintain metabolic homeostasis and orchestrate reparative inflammatory responses. Deregulated autophagy is linked to tumor progression, but the exact mechanisms of selective autophagy in the spatiotemporal control of cell polarity signaling components during cancer metastasis remain ill-defined. Our recent study has demonstrated that TRIM59, an E3 ligase upregulated in metastatic breast cancer, is required for cancer cell survival and metastasis. Genetic depletion of TRIM59 suppresses cancer metastasis by promoting RNFT1-induced K63 polyubiquitination and SQSTM1-directed autophagic degradation of PDCD10, thereby boosting ROCK (Rho associated coiled-coil containing protein kinase)-induced actomyosin contractility and enhancing CDH1-mediated adhesion formation.
