Mechanisms by which phosphorylation may affect drug efficacy. For Class 1 hits, phosphorylation inhibits (⊤) both drug binding and target activity, whereas for Class 2 hits, phosphorylation inhibits drug binding while activating (→) the target. While this schematic depicts phosphorylation inhibiting drug binding, it may in some cases enhance binding as discussed in the text.
