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