Distant metastasis is the leading cause of treatment failure in patients with hepatocellular carcinoma (HCC). However, the underlying mechanisms have not been fully elucidated. Here, we report that Leucine zipper tumor suppressor 2 (LZTS2) is downregulated and correlated with poor prognosis in HCC. Furthermore, we provide evidence that LZTS2 associates with p85 to inhibit the activation of PI3K/AKT signaling and impairs HCC tumorigenesis and metastasis in vitro and in vivo. Moreover, we identify LZTS2 as a bona fide substrate of the E3 ligase β-Trcp and protein kinase CK1δ, which are responsible for the ubiquitination and degradation of LZTS2. Importantly, we show that the β-Trcp and CK1δ-mediated degradation of LZTS2 promotes HCC progression and metastasis by activating PI3K/AKT signaling. Collectively, our study not only illustrates the roles of LZTS2 in regulating HCC tumorigenesis and metastasis but also reveals a novel posttranslational modification of LZTS2 by β-Trcp and CK1δ, indicating that the β-Trcp/CK1δ/LZTS2/PI3K axis may be a novel oncogenic driver involved in HCC progression and metastasis.
