G protein-coupled receptors ( GPCRs) are a large family of cell surface receptors that share a common structure and method of signaling. The members of the GPCR family all have seven different protein segments that cross the membrane, and they transmit signals inside the cell through a type of protein called a G protein (more details below).

G-protein coupled receptors are only found in eukaryotes and they comprise of the largest known class of membrane receptors. In fact humans have more than 1,000 known different types of GPCRs, and each one is specific to a particular function. They are a very unique membrane receptor and they are the target of around 30 to 50% of all modern ...
