Receptor

A receptor is a protein that is able to bind a signaling molecule, a so-called ligand. It is often compared with a key and a lock – the signaling molecule is the key, and when it reaches the receptor, the lock, it leads to an effect. In cell signaling, this effect is often a signaling cascade in the cell, leading to a response.
