CC   -!- FUNCTION: Modulator of macroautophagy that causes accumulation of
CC       autophagosomes under basal conditions and enhances autophagic flux (By
CC       similarity). Represses cell death and promotes long-term clonogenic
CC       survival of cells grown in the absence of glucose in a macroautophagy-
CC       independent manner (By similarity). May have some role in extracellular
CC       matrix engulfment or growth factor receptor recycling, both of which
CC       can modulate cell survival (By similarity).
CC       {ECO:0000250|UniProtKB:A6NC51}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:A6NC51};

CC       {ECO:0000250|UniProtKB:A6NC51}; Multi-pass membrane protein
CC       {ECO:0000255}.
CC   -!- SIMILARITY: Belongs to the DRAM/TMEM150 family. {ECO:0000305}.
