AMBRA1 (Autophagy and Beclin 1 Regulator 1): AMBRA1 is a key protein that regulates autophagy, the process by which cells break down and recycle their components. It supports cell survival during stress by collaborating with BECN1 (Beclin 1) to initiate the formation of autophagosomes. Proper functioning of AMBRA1 is essential for cellular homeostasis, and its dysregulation has been linked to developmental disorders and neurodegenerative diseases.
