Autophagy is a process of intracellular bulk degradation in which cytoplasmic components including organelles are sequestered within double-membrane vesicles that deliver the contents to the lysosome/vacuole for degradation. UVRAG (UV irradiation resistance-associated gene) has been identified as an essential component of the Beclin 1-PI3KC3 complex that suppresses tumorigenicity of human colon and promotes Beclin 1 dependent autophagy.Synonyms: UV radiation resistance-associated gene protein, p63
