Model for SNX5 regulation of HNSCC progression. By interacting with FBW7, SNX5 blocks FBW7-mediated ubiquitination and degradation of oncoproteins such as cleaved NOTCH1, c-Myc, and Cyclin E1. Therefore, expression of SNX5 promotes HNSCC progression. On the contrary, loss of SNX5 enhances the degradation of these oncoproteins and suppresses HNSCC progression.
