Self-phosphorylation is an excellent mechanism for triggering specific catalytic function of the proteins involved in signal cascades because it

changes the shape and thus the enzymatic activity of the proteins involved

makes the receptor more likely to capture the signaling, molecule

allows hydrophilic signaling molecules to cross the plasma membrane
