Required for cytoplasm to vacuole transport (Cvt) and autophagy as a part of the autophagy-specific VPS34 PI3-kinase complex I. This complex is essential to recruit the ATG8-phosphatidylinositol conjugate and the ATG12-ATG5 conjugate to the pre-autophagosomal structure. ATG14 mediates the specific binding of the VPS34 PI3-kinase complex I to the preautophagosomal structure (PAS) (By similarity). Coiled-Coils at the N-terminal half are essential for autophagy. Belongs to the ATG14 family.
