G2E3 (G2/M-Phase Specific E3 Ubiquitin Protein Ligase): G2E3 is an E3 ubiquitin ligase that plays a role in cell cycle regulation, particularly in the G2/M phase transition. It is involved in the ubiquitination and degradation of cell cycle regulators, and its dysregulation can lead to cell cycle abnormalities and contribute to tumorigenesis....
