NRBF2 (Nuclear Receptor Binding Factor 2): NRBF2 is a protein involved in autophagy, a cellular process that breaks down and recycles damaged or unnecessary components. NRBF2 plays a crucial role in regulating autophagy by aiding the formation of autophagosomes, the double-membraned vesicles that engulf cellular materials for degradation. It interacts with the ULK1 kinase complex—which includes ULK1, ATG13, FIP200, and ATG101—enhancing its stability and activity, which is vital for initiating autophagy.
