Gs alpha subunit

The G_s alpha subunit (G_αs, G_sα, or G_s protein) is a heterotrimeric G protein subunit that activates the cAMP-dependent pathway by activating adenylyl cyclase. It is one of the three main families of G proteins: G_αi/G_αo, G_αq, and G_αs.

A mnemonic for remembering this subunit is to look at the first letters in each word (G_αs = Adenylate Syclase).
