Signaling starts with a receptor protein on a target cell detecting a specific ligand that fits its binding domain.
Signaling begins when a receptor protein on the target cell recognizes a specific ligand, which must match the receptor's binding domain.
| Text | Signaling begins with the recognition of a chemical messenger, a ligand, by a receptor protein in a target cell. The ligand much match the receptor's ligand-binding domain. |
