1	Protein monomer Monomer Protein × 1 PDB declaration: monomeric（1） Consistent with protein copy count	Chain B； UniProt 293–887	Fragment：UNP residues 293-887	GOL GLYCEROL × 1 2UG 4'-(cyclopropylmethyl)-N~2~-(pyridin-4-yl)-4,5'-bipyrimidine-2,2'-diamine × 1	X-RAY DIFFRACTION X-ray crystallization conditions：VAPOR DIFFUSION, HANGING DROP；303.15 K；VPS34 protein and PIK-III were mixed and incubated on ice for 1 hr (final PIK-III concentration was 1 mM). Prior to crystallization, the mixture was passed through a 0.2 um filter. The protein:ligand complex was crystallized using the hanging drop vapor diffusion method in Nextal plates: 6 uL of protein solution was mixed with 4 uL of precipitant, which consisted of 20% (w/v) PEG 3350, 100 mM bis-tris propane, and 200 mM Na-K-phosphate. The resulting drop was suspended over a reservoir of 0.3 mL of precipitant and sealed with a screw cap. The crystals grew at 30 degC in approximately 12-24 hr.	Resolution 2.80 Å R-free 0.223
