NRBF2 (Nuclear Receptor Binding Factor 2): NRBF2 is a protein involved in autophagy, a cellular process that degrades and recycles damaged or unnecessary components. NRBF2 plays a key role in regulating autophagy by helping form autophagosomes, the double-membraned vesicles that capture cellular cargo for degradation. It interacts with the ULK1 kinase complex—which includes ULK1, ATG13, FIP200, and ATG101—promoting its stability and activity, which is essential for initiating autophagy.
