AMBRA1 (Autophagy and Beclin 1 Regulator 1): AMBRA1 is a crucial protein that regulates autophagy, the process by which cells break down and recycle their components. It promotes cell survival under stress by collaborating with BECN1 (Beclin 1) to initiate autophagosome formation. Proper AMBRA1 function is vital for cellular homeostasis, and its dysfunction has been linked to developmental disorders and neurodegenerative diseases.
