==Crystal structure of Human Gem G-domain bound to GDP==
-
Gem, a member of the Rad,Gem/Kir subfamily of small G-proteins, has unique, sequence features. We report here the crystallographic structure, determination of the Gem G-domain in complex with nucleotide to 2.4 A, resolution. Although the basic Ras protein fold is maintained, the Gem, switch regions emphatically differ from the Ras paradigm. Our ensuing, biochemical characterization indicates that Gem G-domain markedly prefers, GDP over GTP. Two known functions of Gem are distinctly affected by, spatially separated clusters of mutations.
