AMBRA1 (Autophagy and Beclin 1 Regulator 1): AMBRA1 is a crucial protein that regulates autophagy, the process through which cells break down and recycle their own components. It aids cell survival under stress by collaborating with BECN1 (Beclin 1) to trigger the formation of autophagosomes. Proper functioning of AMBRA1 is vital for maintaining cellular homeostasis, and its malfunction has been linked to developmental disorders and neurodegenerative diseases.
