Cytoplasm . Endoplasmic reticulum membrane ; Peripheral membrane protein . Preautophagosomal structure membrane ; Peripheral membrane protein . Cytoplasmic vesicle , autophagosome membrane ; Peripheral membrane protein . Cytosolic under nutrient-rich conditions (PubMed:19050071) . Following autophagy stimuli , such as starvation or rapamycin induction , predominantly detected in cytoplasmic foci , identified as isolation membranes and autophagosomes (PubMed:19050071) . Accumulates on highly curved PtdIns (3) P enriched autophagic membrane via its BATS domain to sense and maintain membrane curvature (By similarity) . Localizes also to discrete punctae along the ciliary axoneme and to the base of the ciliary axoneme (By similarity) . .
