A ligand-gated ion channel transduces a signal by:
- Acheck_circle
Opening to allow specific ions to cross the membrane
- B
Hydrolyzing GTP
- C
Phosphorylating itself on tyrosines
- D
Activating intracellular kinases first
Explanation
Binding of the ligand causes a conformational change that opens an ion-selective pore, allowing rapid ion flow that changes membrane potential or signaling.
