Abstract
Herein, we present a simple readout of the binding between a chemical drug and its target proteins in the cytoplasm by using a two-step bioorthogonal labeling method combined with spatially-localized expression of proteins. Dasatinib was modified with trans-cyclooctene (TCO), and its cytoplasmic target kinases were expressed in intracellular compartments, such as endosomes and F-actins. After bioorthogonal labeling, the colocalization between Dasatinib and its target proteins was observed in intracellular compartments.
