DNA Damage Regulated Autophagy Modulator 1 (DRAM1) plays pivotal roles in autophagy regulation. Here, the authors show that DRAM1 stabilizes lysosomal VAMP8, thereby promoting autolysosome maturation. Furthermore, they establish that DRAM1–VAMP8 axis enhances autophagic flux and facilitates hepatocellular carcinoma extravasation, as validated in both zebrafish xenograft and mouse metastatic models.
