| Function | Early component of the autophagy machinery being involved in formation of preautophagosomal structures and their maturation into mature phagosomes in response to phosphatidylinositol 3-phosphate (PtdIns3P). Recruits the ATG12- ATG5-ATG16L1 complex to omegasomes, resulting in ATG8 family proteins lipidation and starvation-induced autophagy. Omegasomes are derived from ER and serve as intermediates for genesis of isolation membrane (also called preautophagosome) from ER cisternae membranes. {ECO:0000269|PubMed:23051912, ECO:0000269|PubMed:23291478, ECO:0000269|PubMed:24954904}. |
