Tethering factor involved in autophagy. Involved in autophagosome maturation by promoting the autophagosome fusion with lysosomes: acts by associating with both the ATG5-ATG12 conjugate and phosphatidylinositol-3-phosphate (PtdIns(3)P) present at the surface of autophagosomes. Also involved in selective autophagy against bacterial pathogens, by being required for phagophore/preautophagosomal structure biogenesis and maturation.
Belongs to the TECPR1 family. Contains 1 PH domain. Contains 9 TECPR repeats.
The PH domain mediates the binding to phosphatidylinositol-3-phosphate (PtdIns(3)P). While full-length protein is unable to bind PtdIns(3)P in vitro, it is assumed that the binding to the ATG5-ATG12 conjugate exposes the PH domain, allowing the association with PtdIns(3)P (PubMed:22342342).
Cytoplasmic vesicle > autophagosome membrane. Lysosome membrane. Localizes to Lysosome membranes, and binds PtdIns(3)P at the surface of autophagosome. Localizes to autolysosomes, a vesicle formed by the fusion between autophagosomes and lysosomes.
