Ubiquitination, a critical post-translational modification, regulates diverse cellular processes including protein degradation, signal transduction, and cell cycle progression. Dysregulation of the ubiquitin system is closely associated with tumor development and progression. HERC4, a member of the HECT-type E3 ubiquitin ligase family, remains poorly characterized in colorectal cancer (CRC). In this study, we report that HERC4 is significantly downregulated in CRC tissues and is associated with  ...[more]
