Rapid Screening of a GFP-Tagged Phosphoinositide Probe Library using APEX-GBP Allows for Fast and Reliable Protein Localization

(A?H) GFP-PLC-PH, GFP-BTK-PH, GFP-AKT-PH, GFP-TAPP1-PH, GFP-2xFYVEhrs, GFP-OSBP-PH, GFP-2ML1N and GFP-2ML1N (7Q) detected at known subcellular localizations by APEX-GBP co-transfection. Scale bars represent 1 �m. Untransfected adjacent cells without reaction product. Arrowheads represent enriched electron density at the PM, arrows highlight accumulation of reaction product within endosomes. Cy, cytoplasm; PM, plasma membrane; EEs, early endosomes; LE, late endosomes; Golgi, Golgi complex; M, mitochondria; CCP, clathrin-coated pit. The above localizations were confirmed by confocal microscopy; see Figure S3. Comparisons of ultrastructure between modular and directly APEX-tagged PI probes were performed; see Figures S4A?S4C.
