G protein can refer to two distinct families of proteins.

Further effect depends on the type of G protein.

Further signal transduction depends on the type of G protein.

Different types of heterotrimeric G proteins share a common mechanism.

These G proteins are used in the signal transduction of taste and smell.

Some evidence suggests that receptors and G proteins are actually pre-coupled.

Its activity is mediated by G proteins which activate several different second messenger systems.

The population size has remained constant over the last 70 years and the G protein appears to be the main site of diversifying selection.

In contrast, the G protein differs considerably between the two subtypes.

The clathrin coat is thought to assemble in response to regulatory G protein.
