Catalytic receptor
From Wikipedia, the free encyclopedia
A Catalytic receptor is an integral membrane protein possessing both enzymatic catalytic and receptor functions.[1]
The following is a list of the five major families of catalytic receptors:
| Family | Member | Gene | Catalytic activity | Endogenous Ligands | Synthetic Ligands |
