NBR1 (Neighbor Of BRCA1 Gene 1): NBR1 is a multifunctional autophagy receptor that regulates selective autophagy — the targeted degradation and recycling of cellular components. It aids in the removal of ubiquitinated protein aggregates and damaged organelles, supporting cellular homeostasis and protection against stress. Its role in autophagy is closely linked to disease prevention, including neurodegenerative disorders, cancer, and age-related conditions, underscoring its significance in cellular health and longevity.
