Function

GTP-binding protein that functions as an allosteric activator of the cholera toxin catalytic subunit, an ADP- ribosyltransferase. Involved in protein trafficking; may modulate vesicle budding and uncoating within the Golgi apparatus.

Subcellular Localization

Golgi apparatus {ECO:0000269PubMed:17555535}. Cytoplasm, perinuclear region {ECO:0000269PubMed:17555535}.
