It is also found fused to an inactive Galpha in the Dictyostelium protein gbqA [2]. G-gamma likely shares a common origin with the helical N-terminal unit of G-beta [2]. All organisms that posses a G-beta possess a G-gamma [2].

The G protein alpha subunit binds guanyl nucleotide and is a weak GTPase. A set of residues that are unique to G-alpha as compared to its ancestor the Arf-like family form a ring of residues centered on the nucleotide binding site [3]. A Ggamma is found fused to an inactive Galpha in the Dictyostelium protein gbqA [3].
