RING E3 ligases

RING E3 ligases are a type of enzyme that play a crucial role in the cell's system for regulating proteins. They help attach a small molecule called ubiquitin to specific target proteins, marking them for various fates like degradation or activity alteration. RING E3 ligases act as matchmakers, bringing together the ubiquitin donor enzyme and the target protein to facilitate this transfer efficiently. This process is essential for maintaining cellular health and regulating processes like cell cycle, DNA repair, and immune response. Their precise function ensures proteins are controlled accurately, preventing abnormal cell behavior.
